Ein sehr nützliches Monitoring-Tool ist bekanntlich smokeping

Bei vielen Servern genügt mir ein einfacher Ping, den Smokeping mit 'fping' realisiert, und ich hatte eine alte Version, die dafür völlig genügte.

Damit ich für mutwillig abgeschaltete Server nicht dauernd Emails bekomme, habe ich lange gesucht, um die Variable edgetrigger und ihre Möglichkeit zu finden. Die gibt es erst ab Version 2.0.2

 

edgetrigger:

The alert notifications and/or the programs executed are normally triggered every time the alert matches. If this variable is set to 'yes', they will be triggered only when the alert's state is changed, ie. when it's raised and when it's cleared. Subsequent matches of the same alert will thus not trigger a notification.

When this variable is set to 'yes', a notification program (see the to variable documentation above) will get a sixth argument, raise, which has the value 1 if the alert was just raised and 0 if it was cleared.

Default value: edgetrigger = no


in die Alerts Sektion einfügen:

für alle

oder nur für eine 'loss' Art


    *** Alerts ***
    to = xyz@gmail.com
    from = smokealert@abc.com

    edgetrigger = yes

    +bigloss

    type = loss
    # in percent
    pattern = ==0%,==0%,==0%,==0%,>0%,>0%,>0%
    comment = suddenly there is packet loss

    +someloss

    type = loss
    edgetrigger = yes 

    # in percent
    pattern = >0%,*12*,>0%,*12*,>0%
    comment = loss 3 times  in a row

    +startloss


    usw....


rrd Datenbanken mergen:

http://oss.oetiker.ch/rrdtool/pub/contrib/merge-rrd.tgz

merge-rrd.py is a python script that merges that data found in rrd
files. This assumes that the two rrds are have the same data structure.

The script creates the merged rrd by copying the entries from the new rrd.
If the new rrd has database entries with missing data, then the records
of the old rrd are used instead. This mean that data from the new rrd
will always take precedence over the data in the old rrd.


There's another one : http://www.pintori.it/rrd-merger/
