Hi All,
This may be not be directly related to this exact
requirement, but might be helpful.
We had a slightly different requirement, i.e., to check
whether every device is live or not ( in terms of ping
reachability )
at a shorter interval than 5 minutes of observium's normal
polling cycle.
Hence we developed the following script ( in fact customized
the script found under the "attic" directory of the
observium distribution. )
and is separately being executed as a cron job like the
other poller observium scripts but at one minute interval
and it will just update observium database about the device
status.
We also set the refresh interval of the front page to 60
seconds ( default 500 seconds ) so that we get alerts (
alert boxes ) on the
front panel ( this can be simply extended to other alert
mechanisms )
The normal observium polling does the full snmp parameter
discorvery/polling in the normal way and populate the
database as it is at the normal 5 minute interval and we did
not change or touch any of those scripts and we are happy
with 5 minute interval for other parameters checking.
But for your requirement, in addition to this you might also
need to find a way to add devices to the observium without
snmp :-)
cron:
*/1 * * * * root
/opt/observium/poll-reachability.php >> /dev/null
2>&1
poll-reachability.php:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#!/usr/bin/env php
<?php
chdir(dirname($argv[0]));
include("includes/defaults.inc.php");
include("config.php");
include("includes/functions.php");
include("includes/definitions.inc.php");
$device_query = mysql_query("SELECT * FROM `devices` WHERE
disabled = '0' ORDER BY `device_id` DESC");
if (!$device_query) {
die('Invalid query: ' . mysql_error());
}
while ($device = mysql_fetch_assoc($device_query))
{
$port = $device['port'];
echo($device['hostname']. " ");
if (isPingable($device['hostname']))
{
$status='1';
} else {
$status='0';
}
if ($status != $device['status'])
{
mysql_query("UPDATE `devices` SET `status`= '$status'
WHERE `device_id` = '" . $device['device_id'] . "'");
if ($status == '1')
{
$stat = "Up";
mysql_query("INSERT INTO alerts (importance,
device_id, message) VALUES ('0', '" . $device['device_id'] .
"', 'Device is up\n')");
if ($config['alerts']['email']['enable'])
{
notify($device, "Device Up: " . $device['hostname'],
"Device Up: " . $device['hostname']);
}
} else {
$stat = "Down (ping)";
mysql_query("INSERT INTO alerts (importance,
device_id, message) VALUES ('9', '" . $device['device_id'] .
"', 'Device is down\n')");
if ($config['alerts']['email']['enable'])
{
notify($device, "Device Down: " .
$device['hostname'], "Device Down: " . $device['hostname']);
}
}
log_event("Device status changed to $stat ", $device,
strtolower($stat));
echo("Status Changed!\n");
}
}
?>

Hi Adrien,
Support for non-SNMP devices is currently not planned.

Hi all !
I know that I ask
about a lot of functionalities … but you like me for
that :-)
So I’ll to be as
clear as possible (and as “English” as possible …).
Is it possible to
add a new kind of device that is only polled with ping ?
The primary goal is to know when distant server (hosted
by partners) aren’t reachable without asking to have
access to their snmp daemon and community …
I imagine that it
can be a huge work because it needs to bypass a lot of
code but you could have think about it … ? To be simple
for everyone, this kind of device can be a new sort of
server but without any snmp information (no device panel
/ no ports panel, etc…) and just be polled by the ping.
And when a hosts is down the alerter send a mail / trap
and the index.php put an information box to warn on
“device down” like any others hosts.
