lsf_prometheus_exporter

Prometheus Exporter for LSF based on https://www.gaborsamu.com/blog/lsf_tig/

System Requirements

LSF 10.1.0.15 (Fix Pack 15) or newer
Python 3.11 or newer
Should only be installed on LSF management or management candidate hosts

Run the exporter

Install via pip

Run pip install lsf_prometheus_exporter
Ensure environment variables are set by running $LSF_ROOTDIR/conf/profile.lsf
Run exporter with python -m lsf_prometheus_exporter or lsf_prometheus_exporter

Note: Ensure the user running the exporter is configured as an LSF adminstrator. Otherwise, not all LSF metrics may be captured.

Clone the repo

Ensure LSF cluster is installed and running.
Ensure environment variables are set by running $LSF_ROOTDIR/conf/profile.lsf
Install dependencies with pip install -r requirements.txt
Start exporter with python lsf_prometheus_exporter.py

For statistics from badmin perfmon, ensure perfmon service is started with badmin perfmon start or set SCHED_METRIC_ENABLE=Y in lsb.params

For statistics from badmin rc view, ensure resource connector service (ebrokerd) is running

Test the exporter

Run the following command on the same host on which you started the exporter.

curl http://127.0.0.1:9405/metrics

This assumes that the exporter runs with the default port.

Optional Configuration

Configuring the exporter is done via environment variables.

LSF_PROMETHEUS_DEBUG

Y|N (default N)

Exporter will print debug messages to stdout if set to Y

LSF_PROMETHEUS_POLLING_INTERVAL_SECONDS

Time in Seconds (default 10)

Exporter will poll LSF for data based on this interval

LSF_PROMETHEUS_PORT

Port number (default 9405)

Prometheus HTTP server port.

LSF_PROMETHEUS_BINDING_ADDRESS

Binding address (Default "127.0.0.1")

Prometheus HTTP binding address

LSF_PROMETHEUS_MGR_HOST_ONLY

Y|N (default Y)

For LSF HA deployment where multiple management nodes are configured. Enable this parameter to check if the current management node is active, and only collect metrics if it is. This is to ensure metrics are not duplicated if multiple exporters are installed and running on multiple hosts in the same cluster.

LSF_PROMETHEUS_HOST_STATUS_DETAIL

Y|N (default N)

Enabled detailed status info for lsf_host_status

LSF_PROMETHEUS_EXCLUDE_COMPUTE_NODES

Y|N (default N)

Exclude compute nodes metric collection

LSF_PROMETHEUS_IGNORE_METRICS

String (default "")

The above variable can be used to ignore metrics. Eg: export LSF_PROMETHEUS_IGNORE_METRICS="metric1,metric2,metric3,.........,metricn"

LSF_PROMETHEUS_ASYNC_COLLECTORS

Y|N (default N) Enables the use of asynchronous fetch operations when querying data from LSF

LSF_PROMETHEUS_HTTPS_MTLS_CAFILE
