# Huawei optical modules

Monitors the status of optical modules. This check will monitor the *Temperature*, *Voltage*, *Electrical current* and *optical signal power*

Check Info:


## Check Info *huawei_entity_optical*

* *service*: this check creates the service *Temperature* for each SFP with the interface name as the item
* *state*: **critical**/**warning** if outside the limits
* *wato*: upper and lower limits
* *perfdata*: 
    * Temperature in °C


Sample output

![sample output](/doc/sample_temperature.png?raw=true "sample [SHORT TITLE]")

## Check Info *huawei_entity_optical.current*

* *service*: this check creates the service *Current* for each SFP with the interface name as the item
* *state*: **critical**/**warning** if outside the limits
* *wato*: none
* *perfdata*:
    * Electrical current in Ampere



Sample output

## Check Info *huawei_entity_optical.dom*

* *service*: this check creates the service *DOM* for each SFP with the interface name as the item
* *state*: **critical**/**warning** if outside the limits
* *wato*: lower and upper levels for RX/TX signal power and levels for deviation.
* *perfdata*:
    * RX and TX signal power in dBm
    * RX and TX signal power deviation in dBm

Deviation extension is based on [CheckMK PR #211](https://github.com/tribe29/checkmk/pull/211) *Add deviation power to cisco_temperature.dom* by [*agabellini*](https://github.com/agabellini)

## Check Info *huawei_entity_optical.voltage*

* *service*:  this check creates the service *Voltage* for each SFP with the interface name as the item
* *state*: **critical**/**warning** if outside the limits
* *wato*: upper and lower limits
* *perfdata*:
    * Voltage in Volt
