Hi,
Trying to get the extention Fast-ping (sub-minute) to work.
When I’m simulate a device down (disconnect it from the network), I expect to see an notification in web-gui in ~30 seconds. This is not working 
I have followed the instruction:
$config[‘ping_rrd_step’] = 30;
$config[‘fping_options’][‘retries’] = 2;
$config[‘fping_options’][‘timeout’] = 500;
$config[‘fping_options’][‘interval’] = 500;
cron.d/librenms (note I have >> /tmp/ping instead of /dev/null, this is for debugging only)
- librenms /opt/librenms/ping.php >> /tmp/ping 2>&1
- librenms sleep 30 && /opt/librenms/ping.php >> /tmp/ping 2>&1
- librenms sleep 15 && /opt/librenms/alerts.php >> /tmp/ping 2>&1
- librenms sleep 45 && /opt/librenms/alerts.php >> /tmp/ping 2>&1
This is the ouput from /tmp/ping during 3minutes…
Pinged 7 devices in 0.01s Pinged 7 devices in 0.01s Pinged 7 devices in 0.02s Pinged 7 devices in 0.01s Pinged 7 devices in 0.01s Pinged 7 devices in 0.01s
No detection that the device (one of the 7) is unreachable…
An ALERT is triggered after by “/opt/librenms/cronic /opt/librenms/poller-wrapper.py 16” in cron, but it runs every 5minutes…
But when I trigger the /opt/librenms/ping.php script (not through cron) it works…
Device is disconnected from network
[xxx@LTC9 ~]$ sudo -u librenms /opt/librenms/ping.php
Device 10.69.192.22 changed status to down, running alerts
Rule #2 (Devices up/down (ICMP)):
Status: ALERT
Pinged 7 devices in 2.54s
Devices is reconnected to network again…
[xxx@LTC9 ~]$ sudo -u librenms /opt/librenms/ping.php
Device 10.69.192.22 changed status to up, running alerts
Rule #2 (Devices up/down (ICMP)):
Status: OK
Pinged 7 devices in 0.16s
Devices is reconnected to network again… (running the script one more time)
[xxx@LTC9 ~]$ sudo -u librenms /opt/librenms/ping.php
Pinged 7 devices in 0.16s
