    we have a LDAP server, and there is a file where it writes 0 in the log when replication is OK (green). How can i configure it to have an alarm when it doesnt read 0 in the log ??

    now i want to have an alert when there is anything other than 0 in this log.

    more details probably would have resulted in a quicker and better response.
    logmon does a 'match' no 'do not match'
    if there is a specific range of characters written then could alarm on those or each for more info
    match 1 or 2 - alarm
    match 1 - alarm status 1 crash
    match 2 - alarm status 2 out of memory
    If there is an unlimited number of characters it will write to the file then perhaps at  the advanced tab checked the "match on every run", with a "Send clear alarm". so if the match to 0 is made the alarm is generated and then cleared right away, and if it doesn't match, it will use the "message to send" added in the Standard tab.

    You will need two watchers - one to clear and one to flag the error.

    First one matches on /^0$/ and is a clear. Set the option "Abort on Match" on the advanced tab. This will stop all following watchers from firing. And clear existing errors if one exists.

    Your second watcher matches on /.*/ and sets the error. Only way it gets here is if the first one didn't match a 0 which gives you the "match if not zero" function.
