Regarding Trends status after Network Outage

[BOLLENGIER Eric]

Hi,

I have the same bug (nagios 1.2), in a race condition (after a host
reboot).

ssh down -> reboot -> host up -> ssh down -> ssh up

[1099042385] SERVICE ALERT: test;ssh;CRITICAL;SOFT;1;Connection refused
[1099042445] SERVICE ALERT: test;ssh;CRITICAL;SOFT;2;Socket timeout
[1099042525] SERVICE ALERT: test;ssh;CRITICAL;HARD;3;Socket timeout
[1099042715] HOST ALERT: test;DOWN;SOFT;1;CRITICAL
[1099042725] HOST ALERT: test;DOWN;SOFT;2;CRITICAL
[1099042735] HOST ALERT: test;DOWN;SOFT;3;CRITICAL
[1099042745] HOST ALERT: test;DOWN;SOFT;4;CRITICAL
[1099042755] HOST ALERT: test;DOWN;HARD;5;CRITICAL
[1099042755] SERVICE ALERT: test;ping;CRITICAL;HARD;1;CRITICAL
[1099042935] HOST ALERT: test;UP;HARD;1;PING OK
[1099042935] SERVICE ALERT: test;ping;OK;HARD;1;PING OK
[1099042945] SERVICE ALERT: test;ssh;CRITICAL;SOFT;1;Socket timeout
[1099043005] SERVICE ALERT: test;ssh;OK;SOFT;2;TCP OK

====> BUG ssh is in CRITICAL HARD STATE, but OK is SOFT !!

[1099043265] SERVICE ALERT: test;ssh;CRITICAL;SOFT;1;Socket timeout
[1099043335] SERVICE ALERT: test;ssh;CRITICAL;SOFT;2;Socket timeout
[1099043395] SERVICE ALERT: test;ssh;CRITICAL;HARD;3;Socket timeout
[1099043475] HOST ALERT: test;DOWN;SOFT;1;CRITICAL
[1099043485] HOST ALERT: test;DOWN;SOFT;2;CRITICAL
[1099043495] HOST ALERT: test;DOWN;SOFT;3;CRITICAL
[1099043505] HOST ALERT: test;DOWN;SOFT;4;CRITICAL
[1099043515] HOST ALERT: test;DOWN;HARD;5;CRITICAL
[1099043565] SERVICE ALERT: test;ping;CRITICAL;HARD;1;CRITICAL
[1099043715] HOST ALERT: test;UP;HARD;1;PING OK
[1099043715] SERVICE ALERT: test;ping;OK;HARD;1;PING OK
[1099043745] SERVICE ALERT: test;ssh;CRITICAL;SOFT;1;Socket timeout
[1099043815] SERVICE ALERT: test;ssh;CRITICAL;SOFT;2;Socket timeout
[1099043865] SERVICE ALERT: test;ssh;OK;HARD;3;TCP OK

=====> hier it's ok, because ssh goes up after 2 test

If you want look this bug in your nagios log file, you could use
my simple perl script (see attachment)

PS :
to use it

for i in nagios-*2004*
do
	./mayday_bug_trends.pl $i
done
