Is it possible to enable additional historical metrics ?

Question

Hi everyone,

I am trying to get additional information from the historical performance monitoring, but only 66 of 525 metrics have historical data enabled.

Is it possible to add historical to some of the following?

1: Path = sp.*.blockCache.global.summary.cleanPages

Description = Number of Clean Pages on SP, based on a logical 64 KB page size

Type = fact

Unit = Count

Availability = real-time

6: Path = sp.*.blockCache.global.summary.freePages

Description = Number of Free Pages on SP, based on a logical 64 KB page size

Type = fact

Unit = Count

Availability = real-time

I read the documentation found https://www.emc.com/dam/uwaem/documentation/unity-p-perf-metrics.pdf but I am unable to figure out how to enable historical for these specific paths.

I've already tried:

uemcli -d 10.0.0.1 -u Local/joe -p MyPassword456! /metrics/service set -historyEnabled yes

but no luck....

yes that is correct

for space reasons not all stats that are available live are kept as historical data.

That isnt configurable - If you have specific requests which stats should be included I would suggest to open a product enhancement request.

Thank you @Rainer_EMC This would be a great feature to have to enable additional historical data.

well we do have to keep in mind that the space for storing historical data on the system itself is limited

so it is always a tradeoff what to store vs. for how long and the peformance implications for the tools processing the data

your other option is to use a off-array monitoring tool that polls the live stats and stores it in its own database

or do that yourself via UEMCLI or REST API
