Super Metric Configuration

[AEsansun2]

     I am trying to create a simple super metrics to show the aggr avail in percentage.

Here is what i am using..

(Net App Aggregate: capacity|netappaggregate_total_capacity-Net App Aggregate: capacity|netappaggregate_available_capacity) /Net App Aggregate:capacity|netappaggregate_total_capacity * 100

I tried every option i know .. and it tells me "Formula expression is not valid. Cannot convert number array to number.

any thoughts ?

We don't run NetApp storage so can't really give you a definite answer, but you could try wrapping them with a sum() function to see if it resolves the issue:

(sum(Net App Aggregate: capacity|netappaggregate_total_capacity)-sum(Net App Aggregate: capacity|netappaggregate_available_capacity)) /sum(Net App Aggregate:capacity|netappaggregate_total_capacity) * 100

That should at least mean you are working with numbers rather than one of these which appears to be returning an array.

didn't help. thank you for tyring

Can you give the exact formulas and not the enumerated one? I can re-write for you using the wrapper functions. As sneddo mentioned, and I've discussed on other threads on the communities, you need to convert the array of #s to a single #.. and that is the error you got. TO do this, need to run it through a formula. I always suggest avg(), so that if you ave multiple data points at the same time they'll be avg'd.. anything else won't give you a generally 'true' representation of the value if there 'actually' are multiple (which is rare).

I tried that and it did not work.

My mistake was i was using Attr Kinds as opposed to metrics.

now it's working . Thank you

[mark_j]

Attr kinds will work and should be the preferred way to do it (Axxxxx). You don't need to use metrics (M) typically. You actually don't want to use metrics M unless you absolutely have to (which is rare). Relative reference vs absolute reference..  A(ttribute) vs M(etric)..

[AEsansun2]

well, i can't get metrics to ever work..  here is a simple conversion to TB .. no worky

avg ($RK46:A4455/1024) / 1024

avg (Net App Aggregate: Capacity|Total Capacity (MB)/1024) / 1024

[mark_j]

It wouldn't work the way you have it. Try this: avg($RK46:A4455)/1048576

*Use $This for applying to a specific resource

[AEsansun2]

ok, trying. But when you get a second, can you explain why we should only use Attr kinds and not metrics. The metrics seem to work perfectly.

thank you for your help.

[mark_j]

Metrics are specific instances and don't 'always' give you a relative reference. If you want a truly relative reference, go for attribute#. However if you're target something like an instantiation, sometimes you'll need to refer to a metric#.

[NuggetGTR]

you shouldn't need the avg or sum, and I recommend using the "This" button for metrics as it would apply to all object of that kind.

something like:

($This:M989 / 1024) / 1024

($This:Mem|Total_Capacity_Avg /1024) / 1024

works fine
