Is there any app in Splunk to monitor ups logs or any sample, demo ups monitoring dashboard available which I use as reference.
Sorry , i couldn't find any information. Could you please share any useful link please
Here is some links to how to collect data from APC UPS via syslog and some example dashboards.
Unfortunately there is no ready to use dashboard code examples.
I couldn't found those with quickly looking. But if you googling "Splunk apc ups" you will get some ideas how to get data out with syslog and then just create those dashboards what you are needing (Voltage, reserve time etc.)
