Blank gaps when activating Fast Ping

Help
1

Hello,

We have configured the data polling every 5 minutes as it is set in the configuration.

Recently we have activated the Fast Polling every 1 minute in order to detect any possible micro-cuts that may occur.

The problem that has arisen is that the Fast Polling does not seem to be working properly, since looking at the ping graphs of different devices we find gaps.

Could these gaps be due to a lack of resources in LibreNMS? As we are adding devices and the CPU usage on average is increasing quite a lot.

Thanks.

How many devices? It could be your fping settings. timeout and interval settings determine how long your system waits. Most of the time during fping is waiting, so it is unlikely to be any sort of resource issue.

About 110-120 devices.
In config.php I have the default configuration.

$config[‘fping_options’][‘retries’] = 2;
$config[‘fping_options’][‘timeout’] = 500;
$config[‘fping_options’][‘interval’] = 500;
