How can I check if the replication work fine ? We use the attached PHP plugin in Icinga to monitor the SNMP OIDs provided by Cyrus. I haven't tried this with the newer Prometheus-based system, but it works just fine on 2.5.X systems built with SNMP enabled: Usage: $argv[0] -H -C -s -p -c -w -h -t -d Required: -H [STRING|IP] Hostname or IP address -s Which service name to check: This may be any service defined in cyrus.conf on host being checked. For example: imap, imaps, pop3 lmtp. This is also used as a label for the results. * Note: To receive a list of services supported by host, use the special keyword 'list'. * Note: Services with special characters in their name, such as lmtp[v6], must be quoted; i.e. 'lmtp[v6]'. Options: -C STRING SNMP community string (defaults to `public'). -p Which property to report (and alarm) on (defaults to 'active'): * forks * active * connections ... Warning & critical thresholds are allowed (scalar or range) for all checks. This is primarily a process oriented check script. It's useful to keep an eye on how many of each service's processes are running versus the configured quantity. You may want to take a look at issue 1827 on GitHub in regards to SNMP on Cyrus: https://github.com/cyrusimap/cyrus-imapd/issues/1827 Please note that this plugin relies upon utils.php by Marcel Kühn & Doug Warner: http://doug.warner.fm/nagios-utilsphp-script-for-php-plugins.html Cheers, -nic -- Nic Bernstein n...@onlight.com Onlight Inc. www.onlight.com 6525 W Bluemound Rd., Ste 24 v. 414.272.4477 Milwaukee, Wisconsin 53213-4073 f. 414.290.0335 <> Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/ To Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus

Hi, not exactly a cyrus check, but I recommend checking the mailq length of whatever SMTP server you have. If it is longer than usual, it may indicate spam originating from some of your users. -- Best regards Vladislav Kurz Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/ To Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus
Re: Monitoring cyrusimapd
Hi, Quoting Albert Shih : Hi everyone, I would like to know what kind of monitoring you perform on a cyrus-imapd. Beside classic (check_imap, check_disk, check_cpu etc...) do you have any special thing to monitor about cyrus-imapd. In addition to the normal System monitoring (CPU-, Memory and Disk usage and the Checks if tie services are running, we monitor the Cyrus logs for Critical errors like IOERROR, or Mupdate commit errors. For example do you launch any check on each database ? How can I check if the replication work fine ? No database checks. For Replication we check the size of the "sync" folder to see if the rolling replication log is growing over 1 MB or if average size of the logs was over 500 KB for more than 15 min M.MengeTel.: (49) 7071/29-70316 Universität Tübingen Fax.: (49) 7071/29-5912 Zentrum für Datenverarbeitung mail: michael.me...@zdv.uni-tuebingen.de Wächterstraße 76 72074 Tübingen Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/ To Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus
