check_rrdtraf plugin

[nms]

Hi,

When executing this plugin with a higher unit then bytes, the result is as follows (sample):

Code: Select all

/usr/local/nagios/libexec/check_rrdtraf -f /var/lib/mrtg/10.193.1.3_504.rrd -w 500.0,500.0 -c 800.0,800.0 -l M
OK - Current BW in: .64Mbps Out: .17Mbps|in=.643269Mb/s;500.0;800.0 out=.171962Mb/s;500.0;800.0

Is there a possibility to obtain the values that have 0 float showing as 0.xxMbps instead of a .xxMbps?

Also is there a possibility of taking into consideration low and high thresholds?

Thanks in advance

Yes, you would have to modify the plugin /usr/local/nagios/libexec/check_rrdtraf to add the leading zero if it was less than 1.

Also is there a possibility of taking into consideration low and high thresholds?

This plugin does not take into account ranges or the ability to alert on levels below a certain amount, and unfortunately I do not know of another rrd plugin that does.

The plugin uses bc to do the math which drops the zero. You could pipe the output to awk to print it as a float with a leading zero:

Code: Select all

scale=$SCALE; ($VALUEIN/$SDIVIN)"| bc

becomes:

Code: Select all

scale=$SCALE; ($VALUEIN/$SDIVIN)"| bc | awk '{printf "%f", $0}'

Thanks cdienger.
