Alerts and Descriptions
by Josh Hopper 17 Dec '14

17 Dec '14

How do I set an alert so that if a switch port without a description is not alerted on? I have descriptions on all ports that I want to monitor. I can't shut the others because some should always be up. Logic: If AdminInterface and PortStatus is Down AND PortDescription = "" then Alert Me This is what I have now. I can filter things that have some form of a description but I'm not sure how to use a description that is blank. See image below.

junos logical sub interface state
by Zhenhui Liang 17 Dec '14

17 Dec '14

Hi, I shutdown all unused ports to make the alerter life easier. But after I done so, all good except ae ports sub interfaces still shows on observium as failed even though the main ae physical ports already administratively down. For instace, ae11: show interfaces ae11 Physical interface: ae11, Administratively down, Physical link is Down But observium still complain ae11.0 failed check: show interfaces ae11.0 Logical interface ae11.0 (Index 153) (SNMP ifIndex 982) How do we ignore logical interfaces when setting up alerter? My current condition is: ifAdminStatus equals up ifOperStatus equals down Thank you. —Zhenhui

Observium SNMP polling crashes various Adtran devices
by John Brown 17 Dec '14

17 Dec '14

Hi, We recently installed Observium in an effort to replace our aging Cacti and Nagios systems. We are running the latest code checked out of SVN (We paid the money to Adam for the Professional Version) Today we added 180+ Adtran based devices to the system. All 180+ devices began rebooting. They would become stable for a few hours and then start rebooting again. Important to note that most of these items have been in our network for 3+ years, are running recent code, and have been rock solid stable for their entire service life. Cacti and Nagios poll them every minute and have been doing so for the past 3 years. Insert Observium and the devices start failing. My initial feeling is that there is something in the way Observium does its SNMP. Curious if anyone else has experienced this or something like this. Its caused us to halt putting more devices on Observium. Devices are TA 5000 / TA 352 GPON ONT's, TA 9xx iad's When I add a single device via add_device <name> and then do a discover.php -h new as soon as the code hits ENTITY-SENSOR-MIB the adtran device reboots noc@observium:/home/observium# ./discovery.php -h new Observium 0.14.12.6107 Discovery ont-03.sip.pon-1-6-1.fttx.XXX.YYYYY.net 38 adtran-aos (adtran-aos) Module [ os ] time: 0.0005s Ports : ....

Re: [Observium] junos logical sub interface state

Ok, I added ifDescr !match *.* In the condition, seems working. Although I don¹t feel that clean about it. I would like to only care about physical interface, not logical. But I tried all snmp mibs in the mib list, none of them I found tell you it¹s a logical interface. So I rely on the pattern *dot* in junos to indicate a logical port.

Example alert checkers, and background information
by Moerman, Maarten 16 Dec '14

16 Dec '14

Hey Guys, I had some spare time, and decided to write up some more documentation on alert-checkers for observium, and provide a whole bunch of example alerts which could be adapted for your use: Document: http://www.maartenmoerman.nl/?p=612 I have provided examples for: - Device down - Processor usage is above 80% - Memory usage is above 70% - State sensor is in ALERT state! - Fanspeed is above or under treshold - Traffic exceeds 85% - BGP Session down - Storage exceeds 85% of disk capacity - Port has encountered errors or discards - Port is enabled, but operationally down Let me know if this is helpful and what you'd like to see added/improved.

TEXT/BLOB fields in MySQL
by Eduardo Schoedler 16 Dec '14

16 Dec '14

Hi, Any chance to change text/blob fields to another type in MySQL? # ./tuning-primer.sh TEMP TABLES Current max_heap_table_size = 512 M Current tmp_table_size = 512 M Of 17956 temp tables, 29% were created on disk Perhaps you should increase your tmp_table_size and/or max_heap_table_size to reduce the number of disk-based temporary tables *Note! BLOB and TEXT columns are not allow in memory tables.If you are using these columns raising these values might not impact yourratio of on disk temp tables.* Thanks. -- Eduardo Schoedler

Re: [Observium] Billing per VM host
by Ron Marosko, Jr. 16 Dec '14

16 Dec '14

I think it does. ;-) Meaning, yes, it graphs the 1000v just like it were any other switch. Thus, make sure you have all your "description" entries defined in the interfaces before you discover the device. And the vEth port does not change when the VM gets vmotioned from one host to another, so stats are consistent.

Re: [Observium] Billing per VM host
by Ron Marosko, Jr. 16 Dec '14

I'm running the Cisco freemium version of the Nexus 1000v virtual switch on my ESXi 4.1 boxen, mainly because I needed LACP uplink capability, which was not available in the vSwitch. Then I discovered that you can get SNMP stats on a per-vEthernet port (meaning per host!) from the 1000v. Sweet! The poller takes a bit longer to run on the 1000v, just like it does on all other Nexus products, but well worth having the information. And yes, you can set up traffic accounting based on the polled information. ...Ron Sent from my Verizon Wireless 4G LTE DROID Xavier Beaudouin <xavier.beaudouin(a)hsoftware.com> wrote: >Hi, > >> Are there any plans to include billing per VM host in Observium?.
