[Observium] Re: how can i tune the ping probe for a custom RTA?

24 May 2023


      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.

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

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.

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:
How do I change the RTA threshold ?
thanks
Tony
