Remote syslog to Observium
by Eduardo Schoedler 25 Jul '14

25 Jul '14

I have forgot one device with remote syslog with debug enabled. My syslog table is with 12G, so I had to truncated :). Any chances to implement regexp filter (like bad_if_regexp) to syslog too? Thanks all! -- Eduardo Schoedler

Better poller for Observium
by Alex Povolotsky 24 Jul '14

24 Jul '14

Hello While Observium has a nice interface, it's database lacks foreign keys a lot, and poller.php is AWFUL. It's slow and unreadable. I've started a new, about 40-50 times lighter observium poller https://github.com/tarkhil/observium-poller It supports only SNMP for now, and is work-in-progress. Only os, processor and memory modules are working, and ports is about 50% finished. If anyone is interested, please join. I'm sure to complete SNMP support for Cisco, but quite unsure if I'll be interested in implementing much else. Alex

Interesting experiment with poll over SSH
by Peter Childs 24 Jul '14

24 Jul '14

We have a host about 320ms from our observium node (yes.. The other side of the planet). Doing a full poll circa 650-700ms (including mac and bgp tables... Its a IOS-XR ASR9K ..). Adjusting the Cr/max-reps did increase speeds, and caused several nasty snmpd explosions on the chassis. As a exercise in interest I spun up a VM much closer to the host, unpacked /opt/observium/mibs etc and configured snmp on that remote host. Then did this root@obs1:/opt/observium# diff -c includes/snmp.inc.php.orig includes/snmp.inc.php *** includes/snmp.inc.php.orig 2014-07-23 17:43:53.720274321 +0930 --- includes/snmp.inc.php 2014-07-23 17:56:23.092286235 +0930 *************** *** 333,338 **** --- 333,345 ---- // Add the OID(s) to the strong $cmd .= " ".$oids; + if( $device['hostname'] == 'faraway.router.com' ){ + $cmd = "ssh -i ~x/x.pem x@remote-poller-node -C " . escapeshellarg($cmd) ; + } This was interesting, but the ssh establishment phase for each snmp execution was a lot of overhead.. So I also did this root@obs1:/opt/observium# cat ~/.ssh/config Host remote-poller-node # HostName machine1.example.org ControlPath ~/.ssh/controlmasters/%r@%h:%p ControlMaster auto ControlPersist 10m This means that a ssh 'master instance' was setup at the start of the poll, and hangs around in the background between executions of various snmpcmd's during the poll. Full poll went from 650-700ms -> ~170ms Thought this might be of interest to some people. Cheers, Peter

Alert checks with load average ?
by Xavier Beaudouin 23 Jul '14

23 Jul '14

Dear Observium gurus, Do you know if it is possible to make alert uppon load average (1minutes) like for example if load average if > 5.0 (this is a random value, but here is an idea). Kind regards, Xavier -- Xavier Beaudouin - Senior Network and System Administrator Infrastructure and network director Horizon Software - http://www.hsoftware.com/ 13 rue La Fayette - 75009 PARIS - France Phone: +33 (0)1 4260 9490 Fax: +33 (0)1 44 56 97 01

[SOLVED] Housekeeping not deleting records if you have a stupid number to kill.
by Crozier, Doug 23 Jul '14

23 Jul '14

I have a rather old and crufty installation of Observium (now at 5668) with over 70 million syslog, eventlog, and timing records that are older than 7 days. The first time I ran housekeeping -s to trim syslog messages it took about 30 minutes to return showing 42 million records. Just to be sure I was actually done deleting 42 million records, I re-ran the command. The same 42 million records were found. Meh. I ran the housekeeping in debug mode and noticed that I didn't have posix support installed. So I installed the php-process package and tried again. Still no records deleted. I tried deleting fewer records by keeping 18 months worth and that didn't help either. Here's the debug output from attempting to delete records older than 7 days: [root@xxx ~]# php /opt/observium/housekeeping.php -s -d DEBUG! SQL[SELECT COUNT(*) FROM `syslog` WHERE UNIX_TIMESTAMP(`timestamp`) < 1405322208;] 42123350 syslog entries from before 2014-07-14 15:16:48 will be deleted [y/N]: y SQL[DELETE FROM `syslog` WHERE UNIX_TIMESTAMP(`timestamp`) < 1405322208;] Syslog housekeeping: deleted entries Deleting the eventlog records also fails to remove the records: [root@xxxx observium]# php housekeeping.php -e -d DEBUG! SQL[SELECT COUNT(*) FROM `eventlog` WHERE UNIX_TIMESTAMP(`timestamp`) < 1380059875;] 29289378 eventlog entries from before 2013-09-25 05:57:55 will be deleted [y/N]: y SQL[DELETE FROM `eventlog` WHERE UNIX_TIMESTAMP(`timestamp`) < 1380059875] Event log housekeeping: deleted entries (As an aside, I'm not sure, but there may be a semi-colon missing on the delete statement for event log records.) What I eventually found was that trying to delete this many records exhausts the lock table (?). ERROR 1206 (HY000): The total number of locks exceeds the lock table size Issuing the same command from the mysql CLI and adding a 10,000,000 limit allowed the deletion to work correctly mysql> SELECT COUNT(*) FROM `eventlog` WHERE UNIX_TIMESTAMP(`timestamp`) < 1380059875; +----------+ | COUNT(*) | +----------+ | 28177378 | +----------+ 1 row in set (51.76 sec) mysql> DELETE FROM `eventlog` WHERE UNIX_TIMESTAMP(`timestamp`) < 1380059875 LIMIT 10000000; Query OK, 10000000 rows affected (3 min 40.32 sec) mysql> SELECT COUNT(*) FROM `eventlog` WHERE UNIX_TIMESTAMP(`timestamp`) < 1380059875; +----------+ | COUNT(*) | +----------+ | 18177378 | +----------+ 1 row in set (37.01 sec) Interesting to note that deleting 10 million records at a time with the LIMIT statement doesn't always work. Adjusting the LIMIT up and down eventually got me where I was going. Now that I have it the system down to a reasonable number of records, a nightly/weekly cron job should do just fine. Thanks for the effort you put into this Tom. For me, this was like a hardware upgrade.

I would like to monitor several interfaces pppoe connections. I enabled the feature and vpdn pppoe # $ config ['bad_if'] [] = "pppoe-"; $ config ['poller_modules'] ['cisco-vpdn'] = 1; The process of self discovery did not detect it. The command show vpdn order properly connections. How can I do?
