Hello, I'm having troubles with NSCA. What we have :
- about 47 passive hosts - about 220 passive services Versions : all are redhat servers, with: - NSCA 2.7.2 (latest one) - Nagios 3.1.2 We have a single "nagios aggregator", which collect all NSCA status from the other hosts. What's happening: a host was reinstalled yesterday (say client22), and now it seems NSCA daemon on the aggregator (say server01) doesn't seem to collect data. What I've done: - tcpdump on both client22 and server01, both show me traffic between them, on NSCA default port (5667) - checked iptables rules, all is ok (as tcpdump shows me traffic, that's a confirmation) - trying to push status by hand from client22 to server01; ALL packets are sent successfully """1 data packet(s) sent to host successfully.""". I've done this with a loop like that: for i in $(seq 1000); do /usr/local/bin/submit_ochp $(hostname -f) UP 'Host is up'; sleep 2; done - Enbling debug for nsca on server01 doesn't show me anything interesting. I just don't see where nsca catch up client22 status, and it keeps on saying : Warning: The results of host 'client22.domain.lt' are stale by 0d 0h 2m 0s (threshold=0d 0h 6m 0s). I'm forcing an immediate check of the host. On another hand, it shows me: [1260267958.216051] [016.1] [pid=23191] Check results for service 'Cron service' on host 'client22.domain.lt' are fresh. I really don't know where to find a solution, neither where is the real problem. We have another network with about 200 passive hosts and over 350 passive services, and it works fine. The only differences are : - the working network is debian-only - the working network's NSCA server doesn't do anything else than central nagios server. server01 does some other stuff, like syslog server and collectd server... maybe there's a bottleneck in there, but I can't be sure about that. Does anyone of you have an idea ? Thank you in advance. Best regards, C. -- Cédric Jeanneret | System Administrator 021 619 10 32 | Camptocamp SA [email protected] | PSE-A / EPFL
