Description

Prometheus exporter to collect the inlet temperature of the server using the ipmitool command.

Requirements

• A Go development environment to compile the program.
• ipmitool in the host we want to monitor.

Instructions

Clone the repository

[root@localhost ~] git clone [email protected]:cfm-mpc/ipmitool_exporter.git
[root@localhost ~] cd ipmitool_exporter

Build the exporter

Compile the exporter:

[root@localhost ipmitool_exporter] make 

Run the exporter

Run the binary in the host you want to monitor. You can cofigure a system service for this.

[root@localhost ipmitool_exporter] ./ipmitool_exporter -sensor "Inlet Temp" -address=":5000" -path="/metrics"

View the metrics

Check that the metrics are being exposed succesfully:

[root@localhost ipmitool_exporter] curl -L localhost:5000/metrics
# HELP go_threads Number of OS threads created.
# TYPE go_threads gauge
go_threads 7
# HELP ipmitool_temp Inlet Temperature
# TYPE ipmitool_temp gauge
ipmitool_temp 32
# HELP process_cpu_seconds_total Total user and system CPU time spent in seconds.
# TYPE process_cpu_seconds_total counter
process_cpu_seconds_total 0
# HELP process_max_fds Maximum number of open file descriptors.
# TYPE process_max_fds gauge
process_max_fds 262144

Integration with Grafana

Requirements

• A Prometheus server (accessible through http by the ipmitool_exporter)
• A Grafana server(accessible through http by Prometheus)

Instructions

• Configure Prometheus to scrape the metrics from the host we want to monitor:

[root@prometheus ~] sudo vim /etc/prometheus/prometheus.yml

(...)

   - job_name: "inlet-temperature"
     metrics_path: "/metrics"
     static_configs:
      - targets: ["localhost:5000"]

• Import the dashboard (grafana/inlet-temperature.json) into Grafana: Dashboards->New->Import->Upload JSON file
