in thread comma delimited, syslog parsing

Basically its like i said. In the example that you mentioned you would send something along the following lines:

hostname, Oct 13 2003, 8:00:00, service is down, Error, Oct 13 2003, 12:00:00
The first date and time being the downtime, the second being the uptime.

Its all really static, i wish the setup on the Unix server was more capable. But you email that line(it can take multiple lines now, after i whined to the Unix guy) to the server. And once it is recieved it is saved to a file specific to that host name, in identical format. Periodically, on the Unix server, scripts are run to create reports on the downtime of each server, and the reason it was down(just the error).

The Unix system does nothing beyond that, it does not correlate downtimes and uptimes beyond what i send it. I've fought to get this moved to the server to no avail.

    Ok. You need to create some datastore on your side. I would recommend some lite-weight database, like DBD::SQLite. You would then enter something for the downtime event. When you parse an uptime event, you will find the corresponding downtime event, delete it from your datastore, and send the full message to the Unix server. Something like:
    1. Parse the syslog file.
    2. For each event, do:
      1. If downtime event, enter event into local datastore.
      2. If uptime event, do:
        1. Find corresponding downtime event in local datastore.
        2. If it doesn't exist, error out.
        3. If it does, create string to send to Unix server.
        4. Send string to Unix server.
        5. Delete downtime event from local datastore.

    The reason you want to delete the matched downtime event is you want to trap a duplicate message for the uptime event. (It sounds stupid, but there's very little cost associated and you trap a potential issue.)

    As for how to do it ... knowing what you're trying to do is half the battle. Try your hand at coding up the above pseudo-code. Post here with any problems you run into.

      Thanks for the help. Minor change in direction, but thats what i needed.
