Hello, I have make some tries but I’m still spammed with fake alerting. Delay value is in minute ? How can I debug poller to check if I really lost ping ? (I’m on a 10 gbit backbone network.. I’m really surprise).

Linux Firewall/Conntrack stats
by Attila Nagy 27 Jun '16

27 Jun '16

Hi guys, I wanted to see some firewall statistics (more exactly connection tracking statistics) of some of our Linux servers, but I couldn't find anything alike in Observium. Am I too lame, or is this a non-existing feature? If it is non-existing then could you tell me whether the future plans do involve this? Thanks, Tylla

Debuging slow SNMP-queries
by Markus Klock 27 Jun '16

27 Jun '16

Hey guys, I noticed I have some devices in my network that are responding very slow on just some specific SNMP-queries so I hacked together a small script that will parse the debug-output of Observium poller or discovery and then show you a list of the snmp-commands that took the longest to complete. I wrote a blogpost on how to use it here: http://blog.best-practice.se/2016/06/observium-performance-tuning.html and you can download the script from github: https://github.com/ZerxXxes/observium-logparser [image: Infogad bild 1] It was very helpful in finding what devices needed a software update ;) I hope it can be useful for others too /Markus

Re: [Observium] observium Digest, Vol 71, Issue 24

You should monitor your Dell server using snmp on the idrac itself like its a different device. The most important thing is the global status It will display in alert in the statuses front page. The global status is the color of the led when it's amber you have an issue. Now you will be able to see that in observium as well. Good luck.

SNMP just sometimes has a hickup. Although usually I don’t have these, but in order to prevent panic/heart attacks, I did introduce that 1 time delay on my device down alerts. Haven you applied alert checkers on port-errors all around your network as well? CRC/port errors, and things like these you might want to fix first before you actually get in to device down alerting. Just a simple "ifInErrors_rate gt 0 & ifOutErrors_rate gt 0 on ifType equals ethernetCsmacd” alert-check will give you all these ports. you’d be surprised how much stuff is wrong in an average network. Also certainly check the port to which your observium machine is connected to, and make sure to monitor your observium machine as well, make sure your machine is well specced out. In addition to this, I’ve configured IP SLA on all our core routers to see/verify that latency on our links is within the SLA parameters of our suppliers. Do this before you check on devices down.

Re: [Observium] Delay the alert trigger in case of loss only one ping
by ron＠rjr-services.com 27 Jun '16

I'll echo this sentiment. We were seeing a large number of false positives because of lack of SNMP response from some devices even though they were responding to pings without problem. Setting a delay of 1 reduced the number of alerts we were seeing substantially. We do still get a couple devices that will fail both checks, usually right after the discovery run, and we'll get an alarm on that, but it clears itself next poll. Damn Cat6509s and Nexus 1000Vs. ;-) Sent from my Verizon 4G LTE smartphone -------- Original message -------- From: "Moerman, Maarten" <mmoerman(a)ebay.com> Date: 6/27/16 4:39 AM (GMT-06:00) To: Observium Network Observation System <observium(a)observium.org> Subject: Re: [Observium] Delay the alert trigger in case of loss only one ping -- This message has been scanned by E.F.A.

One of the last things that make me hold on to cacti are these kind of graphs: [cid:image001.gif@01D1C580.2CFF4E30] The graphs are described here: http://forums.cacti.net/viewtopic.php?f=6&t=8520 We have put the most important interfaces on our NOC screen and can immediately recognize if some interfaces are under unusual high load. Is there a way I can achieve something similar with Observium? Thanks, Regards Siegfried

One of my Apache servers do not show

Hi, I've recently added some hosts to my monitored services. - All are running Apache 2.4 so I applied the Apache configuration as described at http://www.observium.org/docs/apps/#apache - All except one show the Apache application info as expected. - Except for the missing Apache info, this site is correctly reported (so general snmp / xinet config are fine) - I have carefully reviewed the different points for this host and Apache config, all is nominal. Which are the points I might have done wrong in the checklist? Which other points not in the checklist should I look at? Thx for your help Bernard
