Units for Performance Monitoring

[gsd_pe]

Hello Friends,

I was not able to get much help on this topic of variables used for performance monitoring units.
For a few performance graphs where I was not able to get graphs I used %.f and %.2f and [min],[max] values for getting graphs

For some of them I am not able to find the right variables to get graphs, few of them are for SQL Writes and reads per sec
Likewise iSCSI writes and reads / sec on a LUN or something like ISCSI Bytes read and written per sec.

Tried using few guidelines on this topic (https://nagios-plugins.org/doc/guidelines.html#AEN200) but no luck.
Do any one of you have an idea about how to use the UNITS of MEASUREMENT (UOM)

Any help is appreciated, thanks in advance.

UOM is specified by characters following the numeric value.

For example, given the following performance date

Code: Select all

rta=0.849ms;3000.000;5000.000;0; pl=0%;80;100;; rtmax=1.497ms;;;; rtmin=0.643ms;;;;

This is actually 4 different performance datasources

Code: Select all

rta=0.849ms;3000.000;5000.000;0;
pl=0%;80;100;;
rtmax=1.497ms;;;;
rtmin=0.643ms;;;;

LABEL is to the left of the =
VALUE is numeric items following =
UOM is non-numeric item following VALUE

In the above example the following are the UOM

Code: Select all

ms
%
rtmax
rtmin

Well I tried using multiple of those options, could you let me know how I can get a performance graph for ISCSI LUNs
I have created counters for ISCSI Bytes Read and ISCSI Bytes Write for my ISCSI LUNS on which my DB sits.

Unfortunately I am able to get a value which I am not able to get in the form of a graph even though I set min and max values.

The below service monitor command give me a output but can not be plotted to a graph
check_xi_service_nsclient!<password>!COUNTER!-l "\\iSCSI Sessions(iqn.2001-05.com.equallogic:0-1cb196-ae04b5221-9700016109a518d1-dbdev)\\Bytes Received"

For some I was able to get it work by adding %.f at the ending like follows
check_xi_service_nsclient!<password>!COUNTER!-l "\\SQLServer:General Statistics\\User Connections","User Connections: %.f" -w 50 -c 100

Any idea on how to get through this ?

What kind of output are you currently getting from running the checks you are using?

[gsd_pe]

ISCSI Bytes Sent and Received are typically numerical values starting anywhere from 48 to 132456. Not particular to the range but I see them a integer values and not floating ones.

A sample output of the command "check_xi_service_nsclient!<password>!COUNTER!-l "\\iSCSI Sessions(iqn.2001-05.com.equallogic:0-1cb196-ae04b5221-9700016109a518d1-amdbdev01-db01b_1)\\Bytes Sent" is giving a integer value of "155326"

I tried manipulating the above command as follows to get a graph
"check_xi_service_nsclient!<password>!COUNTER!-l "\\iSCSI Sessions(iqn.2001-05.com.equallogic:0-1cb196-ae04b5221-9700016109a518d1-amdbdev01-db01b_1)\\Bytes Sent"!"Bytes Sent: %.f" -w 100000 -c 1000000

When I add the above command, the output turns to "0"

Change this:

Code: Select all

I tried manipulating the above command as follows to get a graph
"check_xi_service_nsclient!<password>!COUNTER!-l "\\iSCSI Sessions(iqn.2001-05.com.equallogic:0-1cb196-ae04b5221-9700016109a518d1-amdbdev01-db01b_1)\\Bytes Sent"!"Bytes Sent: %.f" -w 100000 -c 1000000

to this:

Code: Select all

I tried manipulating the above command as follows to get a graph
"check_xi_service_nsclient!<password>!COUNTER!-l "\\iSCSI Sessions(iqn.2001-05.com.equallogic:0-1cb196-ae04b5221-9700016109a518d1-amdbdev01-db01b_1)\\Bytes Sent","Bytes Sent: %.f" -w 100000 -c 1000000

Note: Replace "!" with a ",".

Let me know if this helped.

Tried to change the same as suggested, after doing the change I receive a reply saying "Bytes Received: 0" and there is nothing in graph.
The Graph always shows "0"

[lmiltchev]

Can you show us the exact command that you are running from the CLI along with the output of it? Are you using a similar format to the one below?

Code: Select all

./check_nt -H 192.168.x.x -s password -p 12489 -v COUNTER -l "\\Network Interface(Intel[R] 82579LM Gigabit Network Connection)\\Bytes Total/sec","Bytes Total/sec is %.f" -w 80000000 -c 95000000
Bytes Total/sec is 9504 | 'Bytes Total/sec is %.f'=9504.200000%;80000000.000000;95000000.000000;
