how can i tune the ping probe for a custom RTA?
Hi, I am using the ping probes and I just noticed that it seems to go critical when the RTA is too high....even if the ping is successful...like so: [cid:image001.jpg@01D98D92.10AB1750]
How do I change the RTA threshold ?
thanks
Tony
Hi Tony,
You can customize the command line of the probe. Here is the help output of the check_ping probe
Usage: check_ping -H <host_address> -w <wrta>,<wpl>% -c <crta>,<cpl>% [-p packets] [-t timeout] [-4|-6]
Options: -h, --help Print detailed help screen -V, --version Print version information --extra-opts=[section][@file] Read options from an ini file. See https://www.monitoring-plugins.org/doc/extra-opts.html for usage and examples. -4, --use-ipv4 Use IPv4 connection -6, --use-ipv6 Use IPv6 connection -H, --hostname=HOST host to ping -w, --warning=THRESHOLD warning threshold pair -c, --critical=THRESHOLD critical threshold pair -p, --packets=INTEGER number of ICMP ECHO packets to send (Default: 5) -L, --link show HTML in the plugin output (obsoleted by urlize) -t, --timeout=INTEGER Seconds before connection times out (default: 10)
THRESHOLD is <rta>,<pl>% where <rta> is the round trip average travel time (ms) which triggers a WARNING or CRITICAL state, and <pl> is the percentage of packet loss to trigger an alarm state.
HTH,
Ahmed.

Ahmed, this is great, do you happen to know what the defaults for THRESHOLD are? RTA,PL?

Hi Tony,
I see this in /opt/observium/includes/definitions/entities/probes.inc.php
$probe = 'check_ping'; $config['probes'][$probe]['enable'] = 1; $config['probes'][$probe]['descr'] = 'Use ping to check connection statistics for a remote host.'; $config['probes'][$probe]['args']['default'] = "-H %hostname% -w 15,2% -c 20,5%"; // PING OK - Packet loss = 0%, RTA = 4.85 ms|rta=4.847000ms;15.000000;20.000000;0.000000 pl=0%;2;5;0 // PING OK - Packet loss = 0%, RTA = 0.67 ms|rta=0.668000ms;15.000000;20.000000;0.000000 pl=0%;2;5;0 // PING CRITICAL - Packet loss = 0%, RTA = 63.59 ms|rta=63.589001ms;15.000000;20.000000;0.000000 pl=0%;2;5;0 $config['probes'][$probe]['output'][] = '/^PING (?<status>\S+) - (?<message>Packet loss = (?<packet_loss>\S+), RTA = (?<RTA>\d[^|]+))|/';
I guess that these are the default values -w 15,2% -c 20,5%
Cheers,
Ahmed.
