OpenAM Monitoring Using Prometheus

Original article

Preface

OpenAM can expose SNMP metrics. To expose these metrics to Prometheus we will use snmp_exporter tool, provided by the Prometheus community.

To follow the current manual Docker and Docker Compose should be installed

Configuration files located in this project https://github.com/maximthomas/openam-prometheus

Just clone it and run with docker-compose:

git clone https://github.com/maximthomas/openam-prometheus.git

cd ./openam-prometheus

docker-compose up

Setup OpenAM and SNMP Monitoring

Open OpenAM URL and create a basic configuration (see OpenAM Quick Start Gude){:target=”_blank”})

Enable SNMP in OpenAM. Login into OpenAM console, goto Configure -> Global Services -> Monitoring

OpenAM monitoring

Enable checkboxes Monitoring Status and Monitoring SNMP interface status

Restart OpenAM instance

Setup SNMP Exporter

Open SNMP exporter URL

http://localhost:9116/

SNMP exporter!

Fill the fields: Target: OpenAM hostname and port, for example openam:8085 Module: SNMP exporter module, for example openam

Press the Submit, then you should see something like this:

# HELP authenticationFailureCount Count of unsuccessful authentications - 1.3.6.1.4.1.42.2.230.3.1.1.2.1.10.2
# TYPE authenticationFailureCount counter
authenticationFailureCount 0
# HELP authenticationFailureRate Current Auth failure rate / second based on a fixed preconfigured window. - 1.3.6.1.4.1.42.2.230.3.1.1.2.1.10.4
# TYPE authenticationFailureRate gauge
authenticationFailureRate 0
# HELP authenticationSuccessCount Count of successful authentications - 1.3.6.1.4.1.42.2.230.3.1.1.2.1.10.1
# TYPE authenticationSuccessCount counter
authenticationSuccessCount 0
# HELP authenticationSuccessRate Current Auth success rate / second based on a fixed preconfigured window. - 1.3.6.1.4.1.42.2.230.3.1.1.2.1.10.3
# TYPE authenticationSuccessRate gauge
authenticationSuccessRate 0
# HELP averageDuration Average duration of tokens of the specified type in OpenAM in seconds - 1.3.6.1.4.1.36733.1.2.3.5.1.2
# TYPE averageDuration counter
averageDuration{tokenTableIndex="1"} 1532
averageDuration{tokenTableIndex="10"} 0
averageDuration{tokenTableIndex="11"} 0
averageDuration{tokenTableIndex="12"} 0
averageDuration{tokenTableIndex="13"} 0
averageDuration{tokenTableIndex="14"} 0
averageDuration{tokenTableIndex="15"} 0
averageDuration{tokenTableIndex="16"} 340
......

Setup Prometheus

If you have an existing prometheus instance add to prometheus.yml job openam with a target to SNMP exporter host and port:

  - job_name: "openam"
    params:
      target: ["openam:8085"]
      module: ["openam"]
    metrics_path: /snmp
    static_configs:
      - targets: ["snmp-exporter:9116"]

Run Prometheus and check targets:

http://localhost:9090/targets You should see something like this:

Prometheus target

Then go to Graph and you will be able to add OpenAM metrics to monitor.

http://localhost:9090/graph

Prometheus graph
