Hello again,
After tuning my MySQL and a long weekend I checked my Icinga server
again to see if everything was working fine.
Not quite, the /var/log/messages was filled with messages like this (and
filled the whole filesystem, 128 GB):
Oct 10 10:05:25 prdicin0001 ido2db: Handling client connection...
Oct 10 10:05:25 prdicin0001 ido2db: Successfully connected to mysql database
Oct 10 10:05:25 prdicin0001 ido2db: Successfully connected to mysql database
Oct 10 10:05:25 prdicin0001 ido2db: Successfully disconnected from mysql
database
Oct 10 10:05:25 prdicin0001 ido2db: Successfully shutdown... (PID=30664)
And in the /tmp filesystem Icinga had written over 500 000 'checkxxxxxx'
files, which made the filesystem go over its allowed inodes.
Leaving both the /var and /tmp filesystem unwriteable.
Oops!
Anyone problems like this?
Regards,
Maarten

Hi all,
I have tuned MySQL, mainly using the setting from
/usr/share/mysql/my-innodb-heavy-4G.cnf
a 'service icinga reload' doesn't give any 'Status data OUTDATED'
warnings anymore.
Everything seems to work smoothly. Guess the problem was that the
standard RHEL 6 MySQL config doesn't allow much connections.

Maarten

Dear Icinga users and developers,
After doing a 'service icinga reload'
it looks like it takes about 442 seconds before the status data is
'updated'.
Current Network Status
Last Updated: Tue Oct 4 12:54:38 CEST 2011 - Updated every 90 seconds
[pause]
Icinga 1.5.1 - Logged in as Uncle.X
Warning: Status data OUTDATED! Last status data update was 442
seconds ago!
Should it take so long? Is this normal behavior for Icinga?
System: HP blade 460c G7, with 2 Six-Core Intel Xeon, 2267 MHz and
8192 Mb memory.
OS: Red Hat Enterprise Linux Server release 6.1 (Santiago)
Icinga version 1.5.1 , RPM installation (RPM's are locally made from
icinga.spec found in the official tarball)
DB: MySQL 5.1.52
Configuration is kept as close to the defaults as possible.
Only icinga.cfg attached, other config files (ido stuff) unchanged
except for db_socket and password.
476 hosts and
1691 services are being checked
Machine seems not really busy, neither does our old server with exact
configuration doing Nagios, running on a HP DL-385 (AMD), 2048 Mb
mem, on RHEL4.
sar output of Icinga machine (period of reloading Icinga):
