PoE Power warning thresholds?
by Richard Müller 09 Sep '15

09 Sep '15

Hy *, does anybody know how the PoE Thresholds for Warning and Error State are calculated? [cid:image001.jpg@01D0EB21.9C0FE580] I have got (Juniper EX) switches which can Provide up to 740W but the warning limit is set to 37W for some reason.

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After upgrading a somewhat outdated version Observium CE 0.13.10.4585 to CE 0.15.6.6430 (under PHP 5.5.28), the poller.php started burning excessive CPU: eight running pollers on an 8-CPU machine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

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

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

Rancid
by Lyndon Labuschagne 07 Sep '15

Hi All I see rancid has a “Latest" tab is there an option to view the previous versions? Also after a slight tweak I have UBNT backups too, just not the Air-fibre as yet there is actually a slight difference in the rancid script for those, and I think all the Ubiquity radios are just associated to AirOS or at least a on the CE release I have for testing purposes Lyndon Labuschagne [cid:image001.jpg@01D0D50C.B78C6660] Ground Floor 76 Kyalami Blvd. Kyalami Office Park T: 010 001 6100 C: 084 888 1017 F: 086 768 3587 E: lyndonl(a)mobiletorque.co.za<mailto:lyndonl@mobiletorque.co.za> W: www.mobiletorque.co.za<http://www.mobiletorque.co.za>

Availability Graphing
by Lyndon Labuschagne 07 Sep '15

07 Sep '15

Hi all I have looked around but don't see any information around availability graphing. What we are looking for is a graph per device that can show if there have been any communication drops? I suppose alerts based on packetloss will tell us if there have been issues, but it would be nice to retrospectively go back a day or week etc. Sent from my iPhone
