njmon and nimon Listing Tags, Measures & Statistics

How To


To draw Grafana graphs of the njmon or nimon data from an InfluxDB, you need to know the structure and names of measures and statistics. This blog covers how to find the names and values of these items.
Updated to include IBM Virtual I/O Servers extra measures and statistics (towards the end).

This blog relates to new Nigel's Performance Monitoring software (njmon and nimon), which is an open source project that you can find and download at
  • The njmon command outputs JSON data (the meaning of the "J" in the name) and
  • The nimon command outputs InfluxDB Line Protocol data (the meaning of the "I" in the name)
But the statistic names and values are the same.
The only difference between njmon and nimon is the output format. They share common source code to extract the data from the AIX, VIOS and Linux operating systems.  The data of both commands can be safely placed in the same InfluxDB database, which for historic reasons, we call "njmon".
As the developer, I can get "expert blindness" in thinking every one knows these details. Clearly, that is a mistake which I need to fix with the blog. Even I forget some of the statistics that are available.
Here is how extract from the output details of the tags, measures and statistics.
What are Tags?
Tags are attached to all the stats. The tags are:
  1. "host" = hostname
  2. "os" = operating system like AIX or one of the flavours of Linux like RHEL, SLES or Ubuntu
  3. "architecture" = the computer CPU type like POWER9 (AIX), ppc64le (Linux), x86-64, arm
  4. "serial_no" = Serial number of the server (if available)
  5. "mtm" = "Machine Type Model", an IBM term. For non-IBM hardware, somthing similar is used
These Tags are used to select the data from the InfluxDB database:
  • For particular virtual machines (also called hostname, host or server),
  • Group AIX hosts into a list to select from ,
  • Group Linux hosts into a list to select from,
  • Select all the virtual machines from a particular server (same serial number),
  • Select the servers of a particular type like POWER9 E950 (9040-MR9 Machine Type Model in IBM speak!)
What are Measures?
Next, we have "Measures", which is a InfluxDB term. For computer stats, we have measures like the CPUs, memory, disks, networks, file systems, NFS, configuration details, kernel stats and more.
Each measure then has a number of statistics. For CPU utilisation, as an example, User, System, Idle and Waiting for I/O.  For disks we have: read and write KB/s, transfers per second and block sizes. 
We could extract details of the measures and statistics from the njmon or nimon output. 
  1. JSON is easy to parse in Python (using a Python dictionary).  njmon output the JSON on a single giant line. So the output file needs to be changed for pretty output format (human readable). If you want to read or edit the JSON - use the line2pretty program to do this.
  2. The nimon output is in InfluxDB Line Protocol format, which is one measure per line and can be tackled via a simple shell script.  We use the nimon output as our starting point.
Use shells script following the example:
  On AIX  
$ nimon -s1 -c1 -f  
$ ls -ltr *lp  
-rw-------    1 nag      rtc           39750 Jul 29 10:08 blue_20200729_1008.influxlp  

$ ./nimon_list_stats  blue_20200729_1008.influxlp   >nimon_aix_statistics.txt  

$    On Linux  
$ nimon -s1 -c1 -f  $ ls -ltr *lp  
-rw-rw-r--. 1 nag nag 44340 Jul 10 18:13 silver2_20200710_1813.influxlp  
$ ../nimon_list_stats silver2_20200710_1813.influxlp >nimon_linux_statistics.txt  
Here is the "nimon_list_stats" script (it is also in the download package):
  # nimon_list_stats  
# 1 parameter = the nimon -f output file in InfluxDB Line protocol format  
# Suggest nimon -s1 -c1 -f  
# nimon_list_stats hostname_datetime.influxlp    

echo File: $file  
echo Tags '- Used to graph a specific host, group by OS or model type etc.'  

cat $file | head -1 | awk '{ print $1 }' | sed 's/identity,//' | tr ',' '\n' |  awk '{printf("    %s\n", $1 ) }'    

TAGS=$(cat $file | head -1 | sed 's/,/ /' | awk '{ print $2 }')    

cat $file | sed 's/'$TAGS'//' | sed 's/   $//' >$TMPFILE    
echo 'MEASURES - Trailing "i" means only an integer allowed, otherwise a "string" or floating point number'  
for i in $( cat $TMPFILE | awk '{ print $1 }' | sort | uniq )  
    echo Measure: $(echo $i | tr , ' ' )          
    grep ^$i $TMPFILE | tail -1 | \                  
    sed 's/, / /g' | sed 's/@/+/g' | sed 's/IBM,/IBM/g' | sed 's/ /@/' | \
    awk -F@ '{ print $2 }'  |  tr ' ' '!' |tr ',' '\n' |  \
    awk '{printf("    %s\n", $1 ) }' | tr '!' ' '  
In the blog, we are not going to cover the details of this straightforward shell script. You will need to have a sample of the nimon output to understand it. A sample for AIX and Linux output is in the download package.
This shell script work with
  • AIX Korn shell (ksh)
  • Linux bash
Although, I noticed a different sorting order from the AIX "sort" and Linux "sort" commands.
Note: the measures and statistics to AIX and Linux are very different.
What are Sub Measures?
There are also measures and sub measures.  While there are disk totals and network totals, njmon/nimon also collects individual disks and networks stats. The same goes for CPU, adapters, volume groups and others. The individual statistics of a measure class (like "cpus" or "disks") are what I call sub measures (like "cpu1", "cpu2" or "hdisk0", "hdisk1"). With njmon these are handled with JSON records within the measure JSON records. With nimon these are handled with extra Tags like "cpu=cpu1" or "disk=hdisk0".
How many Measures and Statistics?
For AIX on a small virtual machine 2 CPU cores, SMT=8, 4 disks and 2 networks
  • 22 Measures
  • 116 Sub measures
  • 1450 Statistics
For Linux on Power on a small virtual machine 2 CPU cores, SMT=8, 1 disk and 1 network
  • 14 Measures
  • 71 Sub measures
  • 838 Statistics
Why the large difference?
AIX has the excellent Perfstat C library to supply nearly all the many statistics in a quick and consistent manor. Linux is a mess in this area with dozens of scattered files (many in /proc), dozens of file formats and less statistics generally.
Statistics names and meaning?
For AIX, njmon and nimon use the statistics names as found in the perfstat library. Look in the /usr/include/llibperfstat.h header file for a one line description of most of the stats. The measure names are the perfstat function names to get the data structures.
For Linux, it is tricky! Some is found in the manual pages for the related /proc files.
What makes the output files larger?
If you have 10's or 100's of disks then the number of statistics grow.
If you have "Top Process" statistics switched on (the -P option) and 1000's of processes on then the number of statistics can be massive. One user report TB's of data.  Note: njmon/nimon ignore processes not using the CPU at all. There is a settable threshold (-t option).
If on AIX you have exotic extra resources like Spectrum Scale (GPFS), NFS, Power Processor Pools, VIOS virtual resources, VIOS Shared Storage Pool, many adapters, tape drives, Async I/O then the numbers of stats grows. These are automatically discovered and reported.
If on Linux you have exotic extra resources like Spectrum Scale (GPFS), GPUs, NFS then the numbers of stats grows. These are automatically discovered and reported except GPUs have to be compiled in to the code due to using a library.

Here are lists of the measurement names for AIX and then Linux:

What about the VIOS 3.1 Measures and Stats? 
If you run the njmon or nimon specifically for the VIOS 3.1 with the extra command line options: uvU
  • -v      : VIOS data on virtual disks, virtual FC and virtual networks
  • -u      : VIOS SSP data like pool, pv and LU
  • -U      : VIOS SSP data like -u plus VIOS cluster data. Warning this can add 2 seconds per VIOS in the SSP cluster
Then you get the following extra measures and statistics - only one example of each is shown.
