How can find LUN name in uemcli output for lun response time

Hi,

Thanks for your question. Page 240 https://dell.to/3HyoL2d you can list them there and it eill tell you which lun maps to the sv name. I don’t see a modifier that allows it in the metrics view though. Page 573

Let us know if there is anything else we can help you with.

Thanks.

1- There is other issue when i login to EMC GUI in Storage / Block  it is showing 78 LUN but when i am running uemcli according to previous post it is showing 51 . What is the issue ?

2- When we are using UEMCLI command as I know it is return average latency on LUN . What does mean average here ? As I find out it is show average read and write latency on LUNS . Is that correct ?

3-  In UEMCLI command we are using an interval such as 5 here . Does it mean it is getiing average read and write latency for that LUN for previous 5 second ?

4- Can we get real time read and write latency or response time ?

It might be snapshot luns and production luns instead of just production luns. Yes, average read and write latency. You should be able  monitor in real time if you use real-time instead of a number.

I don't have any snapshot LUN all of my LUNs are production .This is very strange

How can get real time for that latency with uemcli command I could not find anything about it

On page 573 of that guide, all of the ones that show real-time.

 The following command displays the metrics service settings for the metrics with the specified paths:
uemcli -d 10.0.0.1 -u Local/joe -p MyPassword456! /metrics/metric -path
sp.*.storage.lun.*.avgReadSize,sp.*.storage.filesystem.*.writesRate,sp.*.cifs.smb2.basic.re
adsRate show -detail
Storage system address: 10.0.0.1
Storage system port: 443

1: Path = sp.*.storage.lun.*.avgReadSize
 Description = Average read size on this LUN
 Type = fact
 Unit = KB
 Availability = historical, real-time
2: Path = sp.*.storage.filesystem.*.writesRate
 Description = Rate of sp.*.storage.filesystem.*.writes
 Type = rate
 Unit = Requests/s
 Availability = historical, real-time
3: Path = sp.*.cifs.smb2.basic.readsRate
 Description = Rate of sp.*.cifs.smb2.basic.reads
 Type = rate
 Unit = Ops/s
 Availability = real-time

Replace interval 5 with real-time. As for why the LUNs are not showing is there a pattern to which ones are missing? You may want to call phone support and have them go through the logs. 

1- According to uemcli guide follow command return realtime latency on LUN :

uemcli -d 10.20.30.40 -u MON -p password -sslPolicy store /metrics/value/rt -path sp.*.storage.lun.*.responseTime show -interval 5 -count 1 -output csv

but there are an option in that command "interval 5" as I know this means it is calculate avg response in 5 seconds so this is not real time this is for 5 previous second .

2 - As I said before that when I am running that command it cannot show all luns in output for example first time it return data for 50 LUNs , and another run it it returns data for 30 LUNs , ..... Why it is showing difference ?

The syntax you mentioned is not correct :

[root@mon]# uemcli -d 10.20.30.40 -u Monitor -p mon123 -sslPolicy store /metrics/value/rt -path sp.*.storage.lun.*.responseTime show -realtime -count 1
Storage system address: 10.20.30.40
Storage system port: 443

Operation failed. Error code: 0x1000017
Command line parsing failed near "-realtime" token.
There is a syntax error in the command. Please recheck the command syntax. (Error Code:0x1000017)

[root@mon]# uemcli -d 10.20.30.40 -u Monitor -p mon123 -sslPolicy store /metrics/value/rt -path sp.*.storage.lun.*.responseTime show -interval real-time -count 1
Storage system address: 10.20.30.40
Storage system port: 443
HTTPS connection

Operation failed. Error code: 0x5
The value specified for the '-interval' qualifier is invalid: real-time
One or more specified parameters are invalid. (Error Code:0x5)

hmm, ok, in that case I would recommend calling phone support.
