Prometheus exporter for dot-com monitoring

This exporter for the Prometheus monitoring system calls the xmlreporter api from dotcom-monitoring to provide metrics on device status.

dotcom-monitor api format

<DotcomMonitorConfig>
<Site ID="12" Name="device name" State="Up" Status="ACTIVE"/>
<Site ID="35" Name="device name" State="Up" Status="ACTIVE"/>
</DotcomMonitorConfig>

Building this exporter

The exporter can be built using the Go toolchain:

go build -o dotcom_monitor

Using this exporter

The following command will start the exporter, causing it to listen on TCP port 9423:

./dotcom_monitor --dotcom.sites='1234,5422,1232' --dotcom.pid=123457

The exporter has two known reasons for failing a scrape:

• dotcom-monitor did not return a HTTP 200 OK response
• dotcom-monitor returned an empty device list

After a succesful scrape, the device status can be one of the following:

• 0: Status is Down
• 1: Status is Up
• 2: Other possible statuses (e.g. Postponed)

Example metrics output:

# HELP dotcom_device_status Wheter the dotcom alert is active or not
# TYPE dotcom_device_status gauge
dotcom_device_status{id="231",name="My name",status="ACTIVE"} 1
dotcom_device_status{id="123",name="Other Name",status="ACTIVE"} 0
# HELP dotcom_scrape_success Whether scraping dotcom status was successful.
# TYPE dotcom_scrape_success gauge
dotcom_scrape_success 1

Using this exporter in Kubernetes

Setting up the exporter in Kubernetes

First make sure your dotcom_monitor is available in your registry.

# Build the docker container with your registry in the tag.
docker build . -t <YOUR-REGISTRY>dotcom-exporter:0.0.1

# Push the docker image so that it is available for Kubernetes. 
docker push <YOUR-REGISTRY>dotcom-exporter:0.0.1

We took the liberty to provide you a Kubernetes deployment.yaml manifest. You need to replace the following placeholders:

# Format: 12345,5354,1231
<CONFIGURE WHICH SITES YOU WANT HERE>

# This is your account Global Unique Identifier (Configure > Integrations > the Unique Identifier (UID) column).
<CONFIGURE YOUR PID HERE>

# You should use the tag that you used in the previous step.
<CONFIGURE YOUR CONTAINER IMAGE HERE>
