Process Level Alerts in Observium
by Kaustubh Parthasarthy, CLSA 30 Jun '17

Hi Team, First, I would like to subscribe to the Observium mailing list. Second, i am using the Community Edition of Observium. Following are the details: [cid:image001.png@01D2F0C3.971FFA70] I have setup some alert checks to capture the high CPU alerts. I was also successful to capture some alert. PFA the results. I would like to know, if we can also show, which are the top 10 processes, which are running and as a result the utilization is going high. If I can get the output of the top 10 or top 5 processes on the same mail which is attached, this would assist the support teams to troubleshoot. Could you please assist on this as to how can I setup ?

getting multiple random down events Device status changed to Down (ping)
by Ron Culler 29 Jun '17

29 Jun '17

Started getting multiple events "Device status changed to Down (ping) " over the last few weeks with no major increase in number of devices. Issue started on Cento 6.9 install with PHP 5.4, MySQL 5.1 (260 devices) HW - dual - quad core xeon CPUs, 24 GB Ram, RRD, MySQL, OS - with Observium install all on separate SSD drives Observium SVN install 17.6.8672 (rolling) Upgraded PHP and MySQL to PHP70 with opcode caching enabled, MySQL 5.7.18 - no change Spun up a fresh install Centos 7.3, PHP70 with opcode caching enabled, MySQL 5.7.18 (install per docs) HW - dual - quad core xeon CPUs, 24 GB Ram, RRD, MySQL, OS - with Observium install all on separate SSD drives Observium SVN install 17.6.8672 (rolling) $config['snmp']['max-rep'] = TRUE; Currently only 139 devices added To eliminate DNS related issues I have added the devices to /etc/hosts and forced resolution to use it first. Cron has /opt/observium/observium-wrapper poller -w 5 running every 5 min. The devices are not down and if I manually poll the device with a "Device status changed to Down (ping) " notice it responds normally and comes right back up. Was wondering if anyone has seen any behavior like this with this build or before. Also is there a way to skip ping during the poller run and just do snmp, and if so is it something that I can enable globally? Thanks in advance Ron Culler

rrdtoolx
by austin wonderly 27 Jun '17

27 Jun '17

Hello, What would be the correct way to extract rrd data for a certain period of time (last 7 days for example). I'm trying to extract data for the following graph http://imgur.com/a/Gw9y2, although when I open up the data in excel, I'm not able to get anything of use. I used this command to produce an RRD export first: /opt/observium/scripts/rrdtoolx.py addrra netstats-udp.rrd /tmp/testrrd after which I used: rrdtool dump /tmp/testrrd > /tmp/rrd.xml to get the file into an xml format, and finally I imported the xml into excel. I'm trying to put together a list of time stamps and their appropriate data points, so for example: time1 : 22 errors time2: 10 errors time3: 30 errors .... Would it even be possible to extract this kind of data from the RRD files? Thanks for your help, Austin

WAN link monitoring
by Luke Johnson 27 Jun '17

27 Jun '17

Hi, I have looked for previous questions regarding this, but haven't been able to find one, so I apologise if it has been asked/answered before. We have several paths to a remote router that we monitored via it's loopback IP address. Observium does a great job at alerting us when that router is offline, but, I'm unable to find a way to be alerted when we have a single WAN link failure. During a WAN link failure we can still access the remote router via a redundant path, however, we are often not aware that the primary is offline since Observium can still reach the remote router. Apart from checking if utilisation on the link drops below a certain level, is there any other way that I can perform a check and alert on the above scenario? Thanks, Luke

Question on geolocation dropdown menu
by Ed Iwanski 23 Jun '17

23 Jun '17

We have a largish installation and have locations / devices in every state in the US and every province/territory in Canada. We have been adding all of these to Observium and allowing them to be geolocated based on SNMP location strings (works perfectly, thank you) but found that we are running into an issue where the scrollbar is too tall for many average browser screens. There does not seem to be a way to scroll here so there are some locations that will just not be accessible or seen on this dropdown menu. Is there a way to tune or change this? Also any possibility that the states/provinces/territories can be alphabetically listed on the dropdown menu instead of in seemingly order they were added or random? Screenshot attached, there are more locations at the bottom but that was all I could fit on the screen for the capture. Thanks for any input.

snmpv3 context support
by Tomasz.Kwiecien＠nordea.com 21 Jun '17

21 Jun '17

Hi, Are you planning to add snmpv3 context support to observium? I can see that in file includes/snmp.inc.php: switch ($device['snmp_version']) { case 'v3': $cmd = ' -v3 -l ' . escapeshellarg($device['snmp_authlevel']); /* NOTE. * For proper work of 'vlan-' context on cisco, it is necessary to add 'match prefix' in snmp-server config --mike * example: snmp-server group MONITOR v3 auth match prefix access SNMP-MONITOR */ $cmd .= ($vlan) ? ' -n "vlan-' . $vlan . '"' : ' -n ""'; // Some devices, like HP, always require option '-n' Observium adds context vlan-$vlan for cisco switches if $vlan variable is defined. Would be great to have option to add device with context during new device definition (like option to choose transport protocol, port timout etc). Best regards, Tomasz Kwiecień

Change name of monitored device
by Jason Ross 21 Jun '17

21 Jun '17

Hi, I can't seem to locate anything in the doco that helps, happy to refer to that if it exists. Failing that, I have a device name that I'd like to change the name of to reflect a configuration change. Is it possibly to modify the name of the firewall in this case without dropping all of the captured stats etc? Jason
