Python Network or Process Monitoring Scripts for IBM i

Python Network, Process Monitoring and Utility Scripts for IBM i

This repository will be used to share various Python based system monitoring scripts for IBM i systems.

The goal would be that developers and system admins can monitor various services by creating Python scripts and calling them from a QSH/PASE script or from an IBM i process via a CL, RPG or COBOL program using the QSHEXEC/QSHPYRUN commands that are part of the QShell on IBM i command wrappers. https://www.github.com/richardschoen/qshoni

Available samples

pymonping.py - Ping site by host or ip address to see if active.

Example to ping google.com

python3 pymonping.py --host=google.com

Example to ping DSN host 8.8.8.8 with only 3 packets

python3 pymonping.py --host=8.8.8.8  --packets=3

pymonhttp.py - Check web site to make sure site is up or down. Can also scan response data for a selected value.

Example to check if google.com is online using ssl security. Same as https://www.google.com

python3 pymonhttp.py --host=www.google.com --secure=True

Example to check if google.com is online and scan for the word "clientWidth in the results

python3 pymonhttp.py  --host=www.google.com --echoresults=true  --secure=false  --scanvalue=clientWidth --scanresults=true

pymondircrawltodb.py - This script will crawl a directory structure and output all the file info to a DB2 table so the info can be analyzed, filtered and even sorted by object size. This is very useful when you need to locate and determine which directories have the largest objects. This will also crawl a library in QSYS.LIB or all librarys to help determine a library size.

8/31/2023 - Added ability to capture file create, modify and access times from the IFS.

Example to crawl all of the IBM i libraries in QSYS.LIB and list all objects including source and data files and members.

python3 pydircrawltodb.py --dirname /QSYS.LIB  --outputtable tmp.dircrawlpf

Example to crawl library QGPL in QSYS.LIB and list all objects including source and data files and members.

python3 pydircrawltodb.py --dirname /QSYS.LIB/QGPL.LIB  --outputtable tmp.dircrawlpf

Example to crawl all of the IFS system including QSYS.LIB

python3 pydircrawltodb.py --dirname /  --outputtable tmp.dircrawlpf

Example to crawl all of the IFS system and skip QSYS.LIB library objects

python3 pydircrawltodb.py --dirname /  --outputtable tmp.dircrawlpf  --skipqsyslib True

SQL sample to list objects from dircrawlpf in descending object size order to find large objects. Can also use table to generate reports

select * from tmp.dircrawlpf order by ifssize desc

pymondirsize.py - This script processes a directory and all subdirectories to calculate size. Optionally the script can output just the total bytes or it can also list each individual file in a pipe (|) delimited list along with a running total to quickly identify when a large file has been encounterd because the total goes up rapidly.

Example to get the size of the /tmp directory. DO not list any file names, just the total bytes found

python3 pymondirsize.py  --dirname=/tmp  --dirtype=ifs  -listfile=false

Example to get the size of the QGPL library using IFS path name. List file and other object names and the total bytes found

python3 pymondirsize.py  --dirname=/QSYS.LIB/QGPL.LIB  --dirtype=ifs  --listfile=true

Example to get the size of the QGPL library using library name only. List file and other object names and the total bytes found

python3 pymondirsize.py  --dirname=QGPL  --dirtype=library  --listfile=true
