    Does Zabbix handle *reactive* alerts, or only *proactive* alerts ?

    Hi, Quick question...

    In my previous company we used NetCool for our monitoring.
    This was configured to listen for alerts coming from the servers being monitored.

    e.g.
    Server_X would scan log files, like /var/adm/messages, and if there was a problem (e.g. "/var usage > 95%") that server would fire off a message to NetCool with some warning text and a severity alert level. Something like
    ["Warning: /var usage is > 90% (95%)", "3"]
    (So, the "alert message, the (actual usage)" and "the severity level")

    The NetCool display would then pop up an alert in the summary list with the appropriate colour/alert levels, etc.

    My current company is using Zabbix and I was wondering if Zabbix is able to do the same sort of monitoring, e.g. reacting to an incoming alert from a server, rather than actively polling the server(s) for issues?

    The zabbix server we're using (running 1.8.10) is getting a little sluggish these days, probably from all the hosts and services it's monitoring so I'm looking for ways to try and minimise the traffic in/out of the Zabbix server (as well as the servers being monitored)...

    Cheers,
    Rob.

    A quick fix to off-load your zabbix server is to use active agent checks:
    http://www.zabbix.com/documentation/.../activepassive
    (the agents do the "active" checks and send the results to the zabbix server)

    Some other resources reg. performance tuning:
    In the past, quite often Zabbix users have been puzzled regarding some server tuning parameters – for example, how many pollers do they need? It was usually determined based on experience, testing and a bit of guesstimating. No more fuzzy attempts – get hard facts with Zabbix 1.8.5. UPDATED 2011.11.02: new downloadable template version v2 […]

    You can also do monitoring of logfiles etc. but I do it only where it is the last opportunity / making good sense. Think it will make even bigger load on your server, and require more management / configuration.

    Netcool is cool, but have another position / goal then zabbix I think.
