When asking for help and support, please provide as much information as possible. This should include:
- Steps to reproduce an issue.
- The output of
./validate.php
If it’s an issue with the WebUI then please consider including a screenshot and the browser version you are using.
If you are having troubles with discovery/polling include the pastebin output of:
./discovery.php -h HOSTNAME -d | ./pbin.sh
./poller.php -h HOSTNAME -r -f -d | ./pbin.sh
If you need to post any text longer than a few lines, please use a pastebin service such as https://p.libren.ms using non-expiring pastes.

RX/TX values for dBm don’t seem to be mapping correctly.
snmpwalk returns them as:
iso.3.6.1.2.1.99.1.1.1.4.100302213 = INTEGER: 4082
LibreNMS seems to agree:
“poller_type”: “snmp”,
“sensor_oid”: “.1.3.6.1.2.1.99.1.1.1.4.100302213”,
“sensor_index”: “100302213”,
“sensor_type”: “entity-sensor”,
“sensor_descr”: “DOM RX Power For Ethernet2”,
“group”: “SFPs”,
“sensor_divisor”: 1,
“sensor_multiplier”: 1,
“sensor_current”: 4082,
“sensor_limit”: 2.5,
“sensor_limit_warn”: 0.5,
“sensor_limit_low”: -16.4,
“sensor_limit_low_warn”: -14.4,
“sensor_alert”: 1"sensor_custom": “No”,
“entPhysicalIndex”: “100302213”,
However the conversion from reported values to expected dBm doesn’t seem to work. I am unsure if this is a scale error, or something else.
That “sensor_current” is populated pretty much as-is in the dBm:
DOM RX Power for Ethernet2;
Value: 4087 (dbm)
This causes alerts on all ports with transceiver details.
Limit values are pulled in correctly, but the actual power used is not.
High Alarm High Warn Low Alarm Low Warn
Rx Power Threshold Threshold Threshold Threshold
Port (dBm) (dBm) (dBm) (dBm) (dBm)
Et2 -3.89 2.50 0.50 -16.40 -14.40
Interestingly there is:
iso.3.6.1.2.1.99.1.1.1.6.100302213 = STRING: “mW”
Which maybe denotes the correct units for:
iso.3.6.1.2.1.99.1.1.1.4.100302213 = INTEGER: 4082
Hardware polled is: DCS-7280SR
