Re: [Observium] 30 minute poll issue
by Tom Laermans 26 Nov '12

26 Nov '12

The poller doesnt run 'out of time', no hosts are ever skipped. The poller simply runs to completion. If it takes longer than 5 minutes, it simply starts a new one while the other is still running, which may blow up your system in the longer run.

It’s running on an enterprise grade Kingston SSD, along with Cacti. The host is fairly low-load (it only runs a few monitoring systems and a couple of virtual routers). CPU and network load on the physical host for today are: It has a 1GB NIC and I’ve already checked but over the last 4 hours it hasn’t dropped a single ICMP ping to any of the 4 targets I’ve been continuously polling directly from the Observium VM. Three of the targets were repeatedly showing as down, until I suspended a few hosts on the total devices list. For what it’s worth, the other monitoring instance on there (Cacti) has about 7,000 data sources and isn’t missing a single one. It is on a one-minute polling interval and takes between 10 and 12 seconds to complete. Observium has also been flawless up until now. Interestingly, at 19:10 I moved to the poller-wrapper and re-enabled the hosts that I had disabled. Now CPU usage during each poll is approx 2x and the duration of the polling event is now about 45 seconds according to the wrapper. Since that change, I’ve not had a host go down? It could be coincidence, so I’m going to leave it overnight without making any other changes and see if by the morning it has started doing it again. Out of curiosity - is it possible, with a single poller instance (i.e. what I had before) that should a host respond correctly to the first SNMP get / ping, but then take a very long time to respond to the rest of the polls (say 5 seconds per OID), that it could delay the polling process enough for it to run out of time before hitting all the targets? Thus declare the rest it missed as ‘down’ because it never got around to them? I only ask because if this is possible then it could explain why adding more hosts could lead to this as there are a couple which I know are particularly slow to respond. Specifically they are hardware-integrated SNMP modules on systems which run tiny ARM chips and linux 2.4.21-rmk1. They are _slow_ to get their answers back, especially if two systems are concurrently polling them. If it isn’t possible, then that’s obviously off the mark, but the fact that the wrapper (appears) to have resolved it makes me wonder enough to ask :) Cheers!

We did change the loop around the rrdtool binary, but that shouldn't affect polling. Detecting up/down doesn't really have any prerequisites. It does an ICMP ping and a UDP snmpget. If either of those fail to return, and the host isn't already down, it changes the value in the database to down and skips the rest of the poll. There is nothing really code-related that could cause the effects you're seeing, only the return packets failing to reach the PHP process in time. This kind of thing isn't even observed on very, very heavily loaded systems. Is this a virtualised system? adam.

There aren’t any (literally, this system has only Observium on it). I also checked for any processes running at the point of the ‘host down’ events as was also suggested; the only one is the poller / php process itself. Which takes more CPU on every 6th poll, but nothing more interesting than that. If there were other suggestions then I’m really sorry I’ve obviously missed them (which is quite likely as I’ve noticed before some postings from this list have been dropped by our filtering system). Either way, I’m certainly not ignoring you, I think it would be a bit stupid to ignore any advice from the creator of the product which you are having trouble with :) Always suspect the last change you made broke it – so since there were five or six hosts added last week my initial suspicion was maybe the poller was running out of time. The higher number hosts failing, in order, suggested to me that (assuming it polls them in numerical order) again maybe it is running out of time before completing. This was slightly confirmed by removing hosts at random and suddenly the problem went away. I’m just trying to fault-find at the same time as asking for pointers and I’m happy to check anything that anyone on here may suggest. Incidentally I’m just deploying Job’s poller-wrapper script which I’ve been meaning to do for a while but never got around to it. I’ll know in 30 minutes or so if it’s helped at all and I’ll let you know. In the meantime, please do let me know if I’ve missed or ignored something, as I’ve most certainly not intended to – cheers!

In short, every 30 minute the poller decides that approximately a third of all devices (92 in total) are ‘Offline’. They then magically recover on the next poller interval. The devices are not offline, and the Observium host does not loose connectivity (I’ve tested with numerous pings etc. during this predictable failure period). Interestingly, the host on which Observium runs does record these interesting CPU and RAM metrics during that particular polling run: Now, I’m guessing that there is maybe a more substantial ‘discovery’ run or similar every 30 minutes. For some reason, this more intensive run seems to be resulting in a load of devices going allegedly offline. The problem started on Friday around 11pm and has repeated like clockwork since. We are running the latest SVN. I’m a bit uncertain where to start with this one as although it’s predictable I can’t really see anything which would cause it to happen.

Hi I'm having a hard time getting syslog to work. I've enabled the syslog menu in config.php by inserting "$config['enable_syslog'] = 1;" Ive tried using both rsyslog and syslog-ng.

upgrading ios cause new sensors oid appear
by Nikolay Shopik 19 Nov '12

19 Nov '12

Hi, So we just upgraded one our cisco7201 device from 15.0(1)M3 to 15.1(3)S4, and all sensors data disappear, after while it rediscover some of them but using different(?) OID. At least what I see is, old RRD files still exist but no longer updated, here is example new files: mempool-cemp-4.1.rrd mempool-cemp-4.2.rrd mempool-cemp-4.3.rrd and old mempool-cemp-3.1.rrd mempool-cemp-3.2.rrd mempool-cemp-3.3.rrd Temperature sensors move into different MIB? because old files was: sensor-temperature-cisco-entity-sensor-19.rrd sensor-temperature-cisco-entity-sensor-18.rrd sensor-temperature-cisco-entity-sensor-17.rrd and new: sensor-temperature-cisco-2.rrd sensor-temperature-cisco-3.rrd sensor-temperature-cisco-1.rrd All voltage sensors now gone, which is kinda weird, but probably is some kind cisco weirdness or just move them to other MIB. Is this some kind Cisco MIB(OID) mess we have here or something else?

VMware VM's vanished
by Robert Williams 17 Nov '12

17 Nov '12

Hi all, I recently added all our ESXi hosts to Observium, previously they were only in our other systems. I was pleased to see all the VMs appear on it (this didn't work last time I tried about a year ago, which is why they weren't in Observium). However, about an hour later I checked up on them and they have all disappeared; well, sort of: [cid:image001.png@01CDC4B4.8D572B70] All of this 'was' correct (honest) when I first added them. The same is true for all the hosts I've added, although they do all have the correct number of 'blank' entries though? Attached is the slightly cleaned-up output from a debug run on one of the ESX hosts. Any thoughts welcome :) Cheers, Robert Williams Custodian DataCentre email: Robert(a)CustodianDC.com

6500 Fabric Ingress/Egress scale
by Robert Williams 11 Nov '12

11 Nov '12

Hi Guys, Firstly, apologies for the screen-shots / attachments, but they are required to demonstrate the oddness... I think there is a scaling issue on (or I'm not understanding) the Fabric load bars for the Catalyst 6k. In short, the load bars (to the right of the mini-graph) always seem to show zero, or near zero, even though load is not zero. Example below or attached (or missing, depending on how this list handles images :)) [cid:image003.png@01CDBF49.C8C03550] All bars are showing 2% Ingress and 1% Egress. Below is a zoomed in version of the graphic for Slot 1 Fabric 0: [cid:image002.png@01CDBF48.A37B26C0] This shows ingress is 4% and egress is 2% right now. Load is quite low at the moment so it's not an excellent example I agree - but I can honestly say that even when it's high the most I see on those bars is 2%. So, am I being stupid (quite possible) and these bars mean something else or is there some sort of issue with them or their maths? We have 11 of these chassis, and I've checked them all. They all either show zero or are reading 1 or 2% despite having much higher real loads. Such as this one: [cid:image001.png@01CDBF49.E3BFD450] Maybe if anyone else can check their bars and let me know if it's just me? Cheers!

Important: alert mails disabled by default
by Tom Laermans 10 Nov '12

10 Nov '12

Hi, This is a notification about an important change! In some cases, Observium sends out alert emails upon events. While we always advised to disable these as they are mostly rubbish, they were, until now, enabled by default. They are now disabled, since revision 3406. This means that when you update you will no longer receive the alert emails. If you want to keep receiving these alerts after you svn up to r3406 or higher, add this to your config.php: $config['alerts']['email']['enable'] = TRUE Hopefully we'll have a decent threshold/event/alert system soon; ideas about this are very welcome in our IRC channel.

scaling towards >100GE LAGs
by Job Snijders 09 Nov '12

09 Nov '12

Hi all, I was facing some issues with observium and 16x10GE LAGs, where RRD would flip the finger on me. I propose we let the RRDs accept up to a terabit/sec instead of the current 100gigabit/sec limit. In a year or so we can up it again. :-) (or make it a configurable option!) BTW: If you currently have ports which go over 100GE you need to use 'rrdtool dump' -> edit xml file and change "1.2500000000e+10" to "1.2500000000e+11" and then use 'rrdtool restore' to get the XML back into RRD format. root@observium:/opt/observium# diff includes/polling/ports.inc.php.orig includes/polling/ports.inc.php 339,353c339,353 < DS:INOCTETS:DERIVE:600:0:12500000000 \ < DS:OUTOCTETS:DERIVE:600:0:12500000000 \ < DS:INERRORS:DERIVE:600:0:12500000000 \ < DS:OUTERRORS:DERIVE:600:0:12500000000 \ < DS:INUCASTPKTS:DERIVE:600:0:12500000000 \ < DS:OUTUCASTPKTS:DERIVE:600:0:12500000000 \ < DS:INNUCASTPKTS:DERIVE:600:0:12500000000 \ < DS:OUTNUCASTPKTS:DERIVE:600:0:12500000000 \ < DS:INDISCARDS:DERIVE:600:0:12500000000 \ < DS:OUTDISCARDS:DERIVE:600:0:12500000000 \ < DS:INUNKNOWNPROTOS:DERIVE:600:0:12500000000 \ < DS:INBROADCASTPKTS:DERIVE:600:0:12500000000 \ < DS:OUTBROADCASTPKTS:DERIVE:600:0:12500000000 \ < DS:INMULTICASTPKTS:DERIVE:600:0:12500000000 \ < DS:OUTMULTICASTPKTS:DERIVE:600:0:12500000000 ".$config['rrd_rra']); --- > DS:INOCTETS:DERIVE:600:0:125000000000 \ > DS:OUTOCTETS:DERIVE:600:0:125000000000 \ > DS:INERRORS:DERIVE:600:0:125000000000 \ > DS:OUTERRORS:DERIVE:600:0:125000000000 \ > DS:INUCASTPKTS:DERIVE:600:0:125000000000 \ > DS:OUTUCASTPKTS:DERIVE:600:0:125000000000 \ > DS:INNUCASTPKTS:DERIVE:600:0:125000000000 \ > DS:OUTNUCASTPKTS:DERIVE:600:0:125000000000 \ > DS:INDISCARDS:DERIVE:600:0:125000000000 \ > DS:OUTDISCARDS:DERIVE:600:0:125000000000 \ > DS:INUNKNOWNPROTOS:DERIVE:600:0:125000000000 \ > DS:INBROADCASTPKTS:DERIVE:600:0:125000000000 \ > DS:OUTBROADCASTPKTS:DERIVE:600:0:125000000000 \ > DS:INMULTICASTPKTS:DERIVE:600:0:125000000000 \ > DS:OUTMULTICASTPKTS:DERIVE:600:0:125000000000 ".$config['rrd_rra']); root@observium:/opt/observium# Kind regards, Job Snijders -- AS5580 - Atrato IP Networks

Procedure to add a MIB file for a device already monitored by Observium

Hello, I put a MIB file in /opt/observium/mibs/ for a device whose interfaces I already monitor with SNMP. In order to have Observium uses the MIB to monitor all its components do I just run "/opt/observium/discovery.php -h new" again or do I have to modify "config.php" then run "/opt/observium/discovery.php -h new"?

I've followed the installation instructions to the letter, and while I can get to the observium webpage, I can see observium logo and the text "Big Graphs | Widescreen | Not logged in!" on the top right of the page, I can't see anything else. Furthermore, when I look at the HTML source of the page delivered, it ends with " Not logged in!" and not with </HTML> as I would expect. The machine is a brand new Amazon EC3 VM running Ubuntu 12.04.1 LTS. I'd appriciate any help. I don't see anything of interest in the apache logs. The same client (browser) works OK for the live demo. thanks Elad

Hi, I see that the ability to add custom port descriptins is available, but I cannot find any instructions to how to actually do it. What is the procedure for adding custom port descriptions? Regards, Michael Cushard

Device Traffic Graph

Hi, I set up several devices on Obervium, no problem so far, except for the Traffic Graphs which remain empty. For example : http://img4.hostingpics.net/pics/168961data.jpg The RRD file exist, but the data always return 0.00 How can I debug that ? Is there an snmpwalk command to help understand the problem ? Regards,

Various questions (BGP/Discovery/Pseudowires/Hostname truncating)
by Jason Lixfeld 22 Oct '12

First off, let me say thanks to the developers of Observium. This piece of code is one of the most amazing pieces of code I have used for my network monitoring purposes to date. I have a few questions that I'm hoping someone can answer - BGP: ---- I have a few eBGP speakers that live inside a VRF. Observium picks up the VRFs just fine, but the routing tab for the device only seems to show the BGP sessions that exist in the global (non-VRF) table. Is it possible to show the BGP sessions that exist inside a VRF? Pseudowires: ------------ I see lots of data inside the pseudowires table on the observium database, but I don't see any of that inside the pseudowires tab from within a device where I know pseudowires are configured. These pseudowires exist on IOS boxes, IOS-XR boxes and IOS-XE boxes. I do see a few. Observium > Ports > Pseudowires shows me 11 pseuowires. 6 of them are duplicates of one another while 5 are unique. The database shows hundreds. While looking through a ./discovery.php -d I ran against one of our XR boxes, I did see this: Cisco Pseudowires : SQL[SELECT * FROM `pseudowires` WHERE `device_id` = '1'] DEBUG: SNMP Auth options = -v2c -c ************ /usr/bin/snmpbulkwalk -v2c -c ************ -OQUs -m CISCO-IETF-PW-MPLS-MIB -M /opt/observium/mibs udp:router:161 cpwVcID cpwVcID = No Such Instance currently exists at this OID DEBUG: SNMP Auth options = -v2c -c ************ /usr/bin/snmpbulkwalk -v2c -c ************ -OQUs -m CISCO-IETF-PW-MPLS-MIB -M /opt/observium/mibs udp:router:161 cpwVcName cpwVcName = No Such Instance currently exists at this OID DEBUG: SNMP Auth options = -v2c -c ************ /usr/bin/snmpbulkwalk -v2c -c ************ -OQUs -m CISCO-IETF-PW-MPLS-MIB -M /opt/observium/mibs udp:router:161 cpwVcType cpwVcType = No Such Instance currently exists at this OID DEBUG: SNMP Auth options = -v2c -c ************ /usr/bin/snmpbulkwalk -v2c -c ************ -OQUs -m CISCO-IETF-PW-MPLS-MIB -M /opt/observium/mibs udp:router:161 cpwVcPsnType cpwVcPsnType = No Such Instance currently exists at this OID DEBUG: SNMP Auth options = -v2c -c ************ /usr/bin/snmpbulkwalk -v2c -c ************ -OQUs -m CISCO-IETF-PW-MPLS-MIB -M /opt/observium/mibs udp:router:161 cpwVcDescr cpwVcDescr = No Such Instance currently exists at this OID DEBUG: SNMP Auth options = -v2c -c ************ /usr/bin/snmpbulkwalk -v2c -c ************ -OQUs -m CISCO-IETF-PW-MPLS-MIB -M /opt/observium/mibs udp:router:161 cpwVcMplsPeerLdpID cpwVcMplsPeerLdpID = No Such Instance currently exists at this OID That seems to show that pseudowire support for XR isn't there yet? Is that on the road map, by chance? Discovery: ---------- There are a couple of devices that aren't getting discovered for some reason. The IP that their hostname resolves to is within the 'nets' arrays configured inside config.php and I have other SNMP devices that reach those boxes, so I know the SNMP side is sound. Likewise, I can see the device in question in the CDP table of an adjacent device, so I know that part is working as well. I've looked at a ./discovery -d of an adjacent device hoping to see a clue about why the device is being skipped, but nothing is striking out at me. Hostname truncating: -------------------- We name our devices <device><device_number>.<pop>.<city>.domain.tld. In the devices view, it shows the full device name no problem. In the VRF view, for example, however, it shows only <device><device_number>, truncating the pop and city portions. If anyone has any insight or guidance on these issues, I'd be grateful! Thanks in advance.
