Re: [Observium] tplink router

The switch we can detect. The router seems to be reporting a bogus sysobjectid. Do the routers support adsl-mib? Adam.

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.

Disk stats graphs for Equallogic
by Gerwin Krist 09 Sep '15

09 Sep '15

Howdy, Just added our equallogic boxes to observium and although it detects most of the stuff i'm really missing graphs for disk performance (read/writes and iops). If this is correct? Would it be possible to add such a feature? On https://www.zabbix.org/wiki/Monitoring_Dell_Equallogic_Systems is a template for Zabbix. Maybe it's of use. - Gerwin

adding a few 100 devices - group associations
by Ross [Eve IT] 09 Sep '15

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

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
