# Huawei optical modules

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

**NOTE**: This check requires the *huawei_switch* check package from CMK1.6.x FP2 to be installed.\
You also need to change the scan function in *huawei_switch.include* from

```
def huawei_switch_scan_function(oid):
    return ".1.3.6.1.4.1.2011.2.23" in oid(".1.3.6.1.2.1.1.2.0")
```

to

```
def huawei_switch_scan_function(oid):
    return ".1.3.6.1.4.1.2011" in oid(".1.3.6.1.2.1.1.2.0")
```


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.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*: not yet implemented
* *perfdata*:
    * RX and TX signal power in dBm


Sample output

## 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
