Hi,
i have a strange problem i quite don't understand to handle.
Question:
Is Nagios dropping service checks when executing a host event handler?
Situation:
1. We are monitoring 85 Windows Servers with about 630 service checks
being performed. check_ping is being run on all servers.
2. Any and all performance data is being passed to a custom shell
script. Among others, this script is writing the performance data to a
text file
3. The text file containing the performance data is then passed to our
data warehouse in order to generate reports.
Problem:
Per day, there are about 150 checks (Ping) NOT being executed at all.
When checking our external text file, i see (example here) that a check
at 16:23 is missing. Actually, it seems like check_ping at 16:23 was not
executed on ANY host at all.
02-19-2007 16:21:18#SRVDE050#Ping#OK#PING OK - Packet loss = 0%, RTA =
4.24 ms# SRVDE050#02-19-2007 16:21:18#Ping#PING OK - Packet loss = 0%,
RTA = 4.24 ms
02-19-2007 16:22:18#SRVDE050#Ping#OK#PING OK - Packet loss = 0%, RTA =
1.21 ms# SRVDE050#02-19-2007 16:22:18#Ping#PING OK - Packet loss = 0%,
RTA = 1.21 ms
02-19-2007 16:24:45#SRVDE050#Ping#OK#PING OK - Packet loss = 0%, RTA =
7.24 ms# SRVDE050#02-19-2007 16:24:45#Ping#PING OK - Packet loss = 0%,
RTA = 7.24 ms
Problem source could be:
When checking nagios.log, i see that a host event handler was being
executed at that time. Workflow:
1. check_ping reports a problem (host down, for example)
2. nagios executes the configured host event handler
This is the point where it seems to me, that ANY check related to the
same check_command (here: check_ping) are being dropped at that time.
Maybe i am missing something here...?
We use Nagios 2.6.
Any help is appreciated.
Kind regards,
Andreas
