EPICS PVs for Archiver Appliance status

This small tool publishes Archiver Appliance status as EPICS PVs by polling Archiver Appliance BPL metrics with HTTP/JSON data format.

Software environment

This software is developed and tested in the following environment,

• Python 3.11.1

• pcaspy 0.8.0

Sources file

• archiver_status.py: it can be used for either single node or cluster deployment of Archiver Appliance.

Configuration

• Create customized_config.py based on customized_config_example.py to set appliances as list of dictionary which includes url and identity of an appliance node, and add one element to appliances for single node and multiple elements for cluster.
