source: trunk/server/fedora/config/etc/nagios/check_ldap_mmr.real @ 1573

Last change on this file since 1573 was 1342, checked in by mitchb, 13 years ago
Improvements to check_ldap_mmr plugin o Don't put a newline after each replica's output; the Nagios status page only captures the first line, so run them all together on one line. o Don't return immediately upon finding an error; continue to check the other replicas and print status info about them. o If any replicas have issues, upgrade the return from "ERROR" (which is "UNKNOWN" and doesn't cause an alert) to "WARNING" (a replication failure is usually not a problem on the server running the plugin, so it's probably not a CRITICAL issue for that machine).
