Hello,
We’d like to use Grafana dashboards to present graphs for data from LibreNMS and take the path of LibreNMS + Prometheus + Grafana.
A test environment of LibreNMS + Prometheus is set up with
librenms/docker: 1.47-RC1
prom/pushgateway: v0.7.0
prom/prometheus: v2.6.1
It shows that, when the values of the metrics’ keys include special characters, the metrics are not seen on the Prometheus Pushgateway frontend.
Here is a part of sample output of './poller.php -d -h ':
Prometheus data:
ports
array (
‘ifName’ => ‘Gi1/0/3’,
‘ifAlias’ => ‘GigabitEthernet1/0/3’,
‘port_descr_type’ => NULL,
)

‘INOCTETS’ => ‘17069030130’,
‘OUTOCTETS’ => ‘19521044127’,

It would be greatly appreciated if URL encoding of special characters would be added on the support for Prometheus. Thanks very much!!!
