Little bug in event log
by Sander Steffann 17 Feb '15

17 Feb '15

Hi! I just noticed these entries in my event log after moving a server from one datacenter to another: 16s eth0 IPv6 removed: 2001:9e0:803::30/64 16s eth0 IPv6 removed: 2001:9e0:803::30/64 16s eth0 IPv6 added: 2001:9e0:803::30/64 16s eth0 IPv6 added: 2001:9e0:803::29/64 16s eth0 IPv4 removed: 94.142.242.217/28 16s eth0 IPv4 removed: 94.142.242.210/28 16s eth0 IPv4 added: 83.247.10.30/27 16s eth0 IPv4 added: 83.247.10.29/27 As you can see the IPv4 added and removed lines make sense: remove two addresses from 94.142.242.x/28 and add two addresses in 83.247.10.x/27. The IPv6 addresses are wrong though: It *should* have logged two removals from 2a02:898:148::x/64 and two adds in 2001:9e0:803::x/64, but it logs one of the newly added addresses as removed twice. Here is a diff to fix the bug: --- includes/discovery/ipv6-addresses.inc.php 2015-02-06 18:00:03.498755071 +0100 +++ includes_fixed/discovery/ipv6-addresses.inc.php 2015-02-17 01:30:26.334861137 +0100 @@ -196,7 +196,7 @@ { // Delete IP dbDelete('ipv6_addresses', '`ipv6_address_id` = ?', array($entry['ipv6_address_id'])); - log_event("IPv6 removed: $full_compressed", $device, 'port', $port_id); + log_event("IPv6 removed: $full_address", $device, 'port', $port_id); echo('-'); $check_networks[$entry['ipv6_network_id']] = 1; } Cheers!

Ubiquity not detecting correct os or version
by Simon Smith 16 Feb '15

16 Feb '15

Hi All, I’m having an issue here with a few of our UniFi Access Points and Observium Observium detects most of our AP’s as UniFi but for seem reason two of them as being detected as AirOS ? I have no idea why it is doing this! They all have same Firmware and OS installed so why is it detecting it as AirOS instead of UniFi ? I have even compared snmpwalks and they are both identical (oversally data is different, but names, models, etc all the same!) Also ive noticed the correct ones for UniFi, aren’t detecting the firmware version correctly either ? its showing one point as 3.1.12 when infact I’m on 3.2.10 Any help where I should start looking or even ideas for me, would be very helpful Regards Simon

alerts on clear text not html?
by Zhenhui Liang 16 Feb '15

16 Feb '15

Hi, Group Is it possible to configure observium to not send html alerts? Seems from today, html SMS won’t be able to go through cell phone providers. I would like some clear text version of alerts like nagios. Thanks. —Zhenhui

not getting alert email notifications?
by Simon Smith 16 Feb '15

16 Feb '15

Hi All, I have been using the alerts check for all our servers and broadbands fine for months! then outta the blue last week its suddenly stopped sending me emails? the last email i have shows 'Observium Professional 0.14.11.5993' at the bottom of its header and was on the 21st Nov? I can see in the Alert Logging messaging saying Alert Notification sent and Alert_Notify but i never get them? where would be the best place to check or has someone changed a line in the SVN by mistake ??? because i see a few changes related to alerts NOTE: we use a mailcleaner for spam etc… but ive already checked there and the emails don't even hit the server at the time it says it sent in observium? Regards Simon

Adding hosts in auto-discovery fails
by dorje2007＠seznam.cz 16 Feb '15

Hi i tried auto-discovery feature, and hosts cannot be added even though they are resolvable and accessed by ping and SNMP. Manually can be added. here is the debug from the discovery log: SQL[[0;33mSELECT `device_id` FROM `devices` WHERE `sysName` = 'STO-3750-OFF 5' OR `hostname` = 'STO-3750-OFF5'[0m] [0m Discovering new host STO-3750-OFF5 through CDP Host STO-3750-OFF5 resolved as 10.x.x.x Host STO-3750-OFF5 (10.x.x.x) founded inside configured nets, try to adding: SQL[[0;33mSELECT D.`hostname` FROM ipv4_addresses AS A LEFT JOIN `ports` AS P ON A.`port_id` = P.`port _id` LEFT JOIN `devices` AS D ON D.`device_id` = P.` device_id` WHERE D.`disabled` = 0 AND A.`ipv4_address` = 'STO- 3750-OFF5'[0m] [0m Trying v2c community public ...

Auto Discovery without sysNames
by dorje2007＠seznam.cz 14 Feb '15

14 Feb '15

Hi I've started you use Observium mand must say I'm very impressed :-). Very useful and comfortable tool I have question regarding the autodiscovery feature. I read the do here , http://www.observium.org/wiki/Device_Autodiscovery, and one of the condition is that sysName and device name must be same, or resolvable. In our scalable design all over the world it is very difficult, cause there are about 80 domains and strong of the domain itself takes about 20 characters, so we use only hostname resolvable via /etc/hosts. We also cannot use DNS, cause AD DNS is processed by the other department ( in Asia :-) , and it would take a weeks to synchronize it. So the question is, how can i workaround the auto discovery without same sysName and the hostname ? As far as get it, sysName only contains the domain extension of the hostname. we have about 300 routers/switches, so we want to discover them automatically. many thanks Pet

Alert checker for active "Used" memory? Alert for load average?
by Hogan Whittall 14 Feb '15

14 Feb '15

Hi all, I'm trying to set up some more proactive alerts for my hosts and either the mempool options for alerting are too generic or the docs are out of date. I want to have an alert checker triggered for active used memory, does that exist yet? I'm not talking about total used memory, which includes buffers and cache and is caught by mempool_perc for Physical Memory, but the active used memory (See "Used" memory in attached screencap). I can't find any way to make that happen and that would be much more useful than having an alert that includes buffers and cache in the tally. If I were to create an alert for mempool_perc >= 90% using "Physical Memory" then pretty much 100% of my hosts would alert because of buffers and cache being included. I'd also like to catch memory utilization issues before systems start to swap out, so I'd like to avoid having swap usage be the trigger. Is that possible currently or perhaps is it on the to-do list? :) Something else that would be great is to alert for load averages. I know someone else was asking about this a few months back and it wasn't possible at the time, so here's another vote to get it added. Sometimes we have processes get stuck in I/O wait and the only way to catch when this becomes a real problem is with a high load average since processes in this state don't drive up CPU. Currently running 0.15.2.6274. Thanks! -Hogan

Re: [Observium] Auto Discovery without sysNames
by Gert-Jan de Boer 13 Feb '15

I'm guessing he has no rDNS. I would probably make static entries based on their IP address and network segment. For example ap-ams-10-11-12-13. Kind regards, GJ Op 13 feb. 2015 17:56 schreef jorr(a)streamguys.com: Pet, If you have a list of their IPs, you can generate a reverse dns entry of each by doing a NSlookup, take the results and formulate a /etc/hosts entry for each, then pass the rdns names into Observium for discovery of services. The DNS entries to not need to be known in advance this way. Get the names for your hosts file: For ip in ${iplist[@}; do Echo –e –n “$ip\t” Nslookup $ip | grep <fordnsname> } This way you just need their IP addresses (and a functioning rdns entry) to get all of the devices into the software.

The point is that i have a hundreds of Cisco AP's and dozen of switches all around the world, that i do not now about their IP's and particular location.. They all have CDP running so i would have to first log to those switches and check their names,neighbors, relations and so on. And this i would like to avoid. Different departments configure devices and not all of them are known ( we operate in 60 countries ). So is there a way to discover them without being known by the DNS or hosts file ? ( there is a netdisco tool, that can manage it , however i prefer Observium cause it is more powerful ) Many Thanks Pet . ---------- Původní zpráva ---------- Od: Tristan Rhodes <tristanrhodes(a)weber.edu<mailto:tristanrhodes@weber.edu>> Komu: Observium Network Observation System <observium(a)observium.org<mailto:observium@observium.org>> Datum: 13. 2. 2015 16:04:15 Předmět: Re: [Observium] Auto Discovery without sysNames Pet, The wiki you linked to has the solution: Alternative: Add lines to the "/etc/hosts" file on Observium that match the hostnames and domains that you have configured in your devices.
