Error Drawing Graph
by Chip Pleasants 14 Sep '15

14 Sep '15

Hi All, I'm seeing "error drawing graph" on several of our Cisco ASR's interfaces, so I'm hoping someone coupe point me in the right direction. I'm running Centos 6.6 with the latest rrdtool rrdtool-1.3.8-7.el6-x86_64 and CE version 0.15.6.6430. I've removed the specific graph rrd file then run the following two commands for debugging purposes. php ./discovery.php -d -h router.local.com php ./poller.php -d -h router.local.com. The file is 0 bytes for some reason. Oddly enough two of the three interfaces issues are with BDI interfaces. The weird part is there is one BDI interface on each box that is displaying correctly. Let me know if you any anything else to assist in troubleshooting. Thanks, Chip Port BDI3004(62) replacing with 64-bit... dot3Duplex, VLAN == TELECOM TRANSIT // CID: // CONTACT: ifInOctets (583452815 B) 2244049.2884615 Bps 260 secs ifOutOctets (34747474 B) 133644.13076923 Bps 260 secs ifInErrors (0 B) 0 Bps 260 secs ifOutErrors (0 B) 0 Bps 260 secs ifInUcastPkts (5021371 B) 19312.965384615 Bps 260 secs ifOutUcastPkts (50407 B) 193.87307692308 Bps 260 secs bps(17.9Mbps/1.07Mbps)bytes(556MB/33.1MB)pkts(19.3kpps/193pps)RRD[%g/usr/bin/rrdtool create /opt/observium/rrd/router.local.com/port-62.rrd \ 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 --step 300 RRA:AVERAGE:0.5:1:2016 RRA:AVERAGE:0.5:6:2976 RRA:AVERAGE:0.5:24:1440 RRA:AVERAGE:0.5:288:1440 RRA:MIN:0.5:6:1440 RRA:MIN:0.5:96:360 RRA:MIN:0.5:288:1440 RRA:MAX:0.5:6:1440 RRA:MAX:0.5:96:360 RRA:MAX:0.5:288:1440 %n] rrd_dontneed: Argument 'rrd_file' is NULL.

Hi, Im setting up Observium on ubuntu server 14.04.1 LTS. Using the guide: http://www.observium.org/docs/debian_ubuntu/ All going well until I get to the SQL database bit and have issues: mysql -u root -p <mysql root password> mysql> CREATE DATABASE observium DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci; mysql> GRANT ALL PRIVILEGES ON observium.* TO 'observium'@'localhost' -> IDENTIFIED BY '<observium db password>'; I assume the <observium db password> is to be replaced with a password?

Hi all, I will be accessing my observium from the outside. Therefore i have installed my wildcard cert and enabled https... my problem is when i recive the alert email from observium for some machine. in the email there is a link under device so that i can easily access the server and see what is wrong. my problem is per default the url starts with http and not https. and so the tunnel is not encrypted. How do i change this behaviour?

Tape Libraries in observium
by Steffie Morris 12 Sep '15

12 Sep '15

Hi, has anyone ever tried to add tape libraries in observium? I have an HP MSL6030 and a Dell TL2000 here that i tried to add, but there is no support at all for them yet. I don't know where to start to even try to add some basic information about these devices so i have some reading and catching up to do. But if anyone already has some information, just throw it at me :)

Juniper stack polling - better but still hurting
by Aaron Finney 12 Sep '15

12 Sep '15

Hello all, Moving forward with our POC, and almost everything is perfect...the one thing that's still nagging us is the long polling times for our Juniper switch stacks. Our newest QFX 5k 96s 2-member stacks are now down under 300 seconds after upping max-requests to 70 (~230 seconds now), but our older EX stacks are still taking longer than the polling interval (~330 seconds) to complete. I realize it's the length of time that the Junipers take to handle the snmpbulkwalk of IfEntry and IfEntryX, but has anyone come up with a workaround to date? Obviously stripping OIDs out of the standard MIBs is not a solution because it could break other devices, but is there a possibility I could create an "IfEntry-lite" version that would be exclusive to the EX platform? Or even a custom poller that uses JunoScript instead of snmp? I'm looking for any reasonable solution, even if it takes some work to implement. Thanks!

Support for Nortel/Avaya
by AJ Schroeder 09 Sep '15

09 Sep '15

Hello list, Let me get this out of the way; I am not a developer. Anyway, I have the pleasure of supporting a network that has older Nortel and Avaya devices on it. I've added them to observium and as expected they are showing up as generic devices. I browsed through the developer section on how to add new device support and I have followed those steps and have added some very basic support for Nortel switches (OS version and Serial Number) First question - would this extra support be of any interest to the Observium devs? I'd like to add more meaningful information such as CPU/Memory utilization, flash usage, etc. However, that step appears to be a bit more challenging. Second question - is this documented somewhere or do I need to "reverse engineer" this support from the existing scripts? Any help or suggestions are appreciated. Thanks, AJ Schroeder

unix agent issues
by Robbie Wright 09 Sep '15

09 Sep '15

Trying to get the unix agent setup on a machine with bind to test it out. The scripts for Observium and bind are working on the local machine, but Observium isn't showing the modules. The module is enabled for the device but when trying to telnet from Observium, we're just getting "Connection closed by foreign host." Xinetd is running and listening on the port but isn't responding correctly. There are some typos on the agent installation page on the site (/usr/lib vs /usr/bin) and in the xinetd conf file, but we seem to have those straightened out. Anyone have any tricks up your sleeves for getting the agent to be happy with life? ufw/iptables is off for testing on Ubuntu 14.04 and we're running the subscription edition.

by Ross [Eve IT] 09 Sep '15

Hi all, I'm looking at adding a few 100 devices to Observium shortly. I don't see any issue adding them, as I can use a filename structured as requested. This is for a few clients of ours, I'd like to trial observium as a customer facing solution. Add a user to view their devices only. Is there a way to script giving a user access to so many devices ? Perhaps to group them. Has anyone done this and found issues with a large number of devices ? Regards, Ross.

poller.php burns all available CPU in the last community edition
by Mark Martinec 09 Sep '15

After upgrading a somewhat outdated version Observium CE 0.13.10.4585 to CE 0.15.6.6430 (under PHP 5.5.28), the poller.php started burning excessive CPU: eight running pollers on an 8-CPU machine started burning 100% of available CPU time instead of a few percents as before. They somehow still managed to get their job done, but just barely so in five minutes, and often missing the time slot. While watching the behaviour for a day and learning PHP profiling along the way, I now have an explanation and a solution. Apology if this has been reported before, couldn't find any such report. The problem is in a function external_exec() in includes/common(.inc).php, which has been rewritten some time between these two versions, now switching to a common loop waiting with a stream_select() on two pipes (stdout and stderr) from a spawned snmp*walk process. The documentation on stream_select helps understanding the issue: http://php.net/manual/en/function.stream-select.php read The streams listed in the read array will be watched to see if characters become available for reading (more precisely, to see if a read will not block - in particular, a stream resource is also ready on end-of-file, in which case an fread() will return a zero length string). So what happens is that when a spawned snmp* command closes its stderr but not yet its stdout, the external_exec() goes in a spin: feof($pipes[1]) is false but stream is not yet ready for reading, however the feof($pipes[2]) is true and hence the stream_select() returns right away and reports $pipes[2] as ready. Then the fread($pipes[2]) is called, returns an empty string (because stderr is at eof), and the whole loop busily goes around, until the time the snmp command happens to terminate. Here is a fix: --- includes/common.inc.php.ori 2015-09-04 20:29:39.561244285 +0200 +++ includes/common.inc.php 2015-09-04 20:30:07.617242602 +0200 @@ -618,9 +618,13 @@ { $start = microtime(TRUE); - //while ($status['running'] !== FALSE) - while (feof($pipes[1]) === FALSE || feof($pipes[2]) === FALSE) + while (TRUE) { + $read = array(); + if (!feof($pipes[1])) { $read[] = $pipes[1]; } + if (!feof($pipes[2])) { $read[] = $pipes[2]; } + if (empty($read)) { break; } + stream_select( - $read = array($pipes[1], $pipes[2]), + $read, $write = NULL, $except = NULL, Regards Mark

Cisco ASR Zone Based Firewall graphing
by Willie Van Waveren 08 Sep '15

Hi Observium team, I recently installed Observium and got it running on a bunch of devices. I am now trying to get it to graph zone based firewall stats on Cisco ASR and also ISR. When I go into settings on the devices and click to enable the firewall graph it seems to enable, but then when I go and look again it is back to disabled. Am I missing anything? I would like to have the following in the firewall graph, how can I edit, or add a new one for all Cisco ZBF. 1.3.6.1.4.1.9.9.491.1.1.1.4.0 "The number of connections which were attempted to be setup but which were declined due to non-availability of required resources. This value is accumulated from the last reboot of the firewall." 1.3.6.1.4.1.9.9.491.1.1.1.5.0 "The number of connections which are in the process of being setup but which have not yet reached the established state in the connection table." 1.3.6.1.4.1.9.9.491.1.1.1.6.0 "The number of connections which are currently active." 1.3.6.1.4.1.9.9.491.1.1.1.11.0 "The averaged number of connections which the firewall establishing per second, averaged over the last 300 seconds." Regards, Willie
