Hi list,

our setup is very similar to Tom Stolle's: 3.0b5. No NDO, no embedded_perl =
, but large_installation_tweaks=3D1.
At the moment we have 357 hosts with ~1000 services but plan to increase up=
to 500 hosts / 2000 services per Nagios server.

With the reduced host/service number we have very reasonable latency values=
below 1 second. But in the attached load chart you can see the slow but pe=
rmanent rise of overall load, which forces us to restart Nagios every week.

I just added Ethans auto_schedule-Options to our setup and - see and smile =
- latency is fallen to about 50%!=20
For the load increase it's to early for a statement, I'll come up with an u=
pdate tomorrow.

Cheers,
Matthias

Dear List,

I can confirm the problem describedby Hendrik.
I am using Nagios3.0b5 without NDO,embadded Perl disabled and large_install=
tion option enabled.
Each nagios server is monitoring about1000 hosts (active hostchecks) and so=
meting between 2000 and 5000 services.
When starting nagios (first few hours)latency, execution time and systemloa=
d are normal.

After a few hours load, latency andexecution time start rising.=20
On my systems it is not exactly after8 or 11 hours but is rising continuous=
ly.
A restart of nagios brings all valuesback to normal before they grow again.

My Nagios 2.9 server with exactly thesame hosts monitored does not show any=
problems with latency or executiontime so it is not a problem in the netwo=
rk.

Best regards
Thomas
