Devmon VERSION 0.21.06.06, fork at SF version 0.3.1-beta1 r256
======================================================================
THIS IS NOT AN OFFICIAL VERSION from the original developers:
- Look at SourceForge version for it !
- Previous modified devmon version in this repo were reported
(in 2017) to be less stable than the SF one...
- Use it at your own risks !
SEE END OF FILE for detailled STATUS and ROADMAP!
9 jun 2021, Bruno Manzoni
======================================================================
0.21.06.09 Changes
New features
- CPU revamp (Cisco, Huawei), mainly the "uptime" part
- Reboot cause analysis with a auto disable timer
- Better Uptime value, calculation with (snmp and system oid)
- Threshold automatch acccept multiple value
- We can have not multiple empty (automatch) threshold for an oid
- Empty threshold of the current color is prefered
Bug resolved
- MATH transform with constant (without other deps oids)
- TSWITCH calc
- Perl 5.28 compatibility
- Threshold calculation
- Custom threshold in hosts.cfg should overide other
- BEST threshold can override herited error
And some more !!!

What is Devmon ?
---------------------------------------
Devmon is a Perl software that uses SNMP to monitor, graph and alert
on host information
What are Devmon's prerequisites?
---------------------------------------
In order for Devmon to do anything useful, you will need
a machine capable of running the Perl interpreter, which
is used to execute the Devmon code.
In addition, you will need a machine (either the same machine
running Devmon, or a different one) runing either the Hobbit/Xymon
or BigBrother monitoring program, which displays the messages
that Devmon generates.
Finally, you will need your to have your Hobbit/Xymon or BigBrother
program set up to monitor at least one host that Devmon has
a template for. Only then will Devmon be able to poll a
remote host and display the results. For more information on
Devmon's template system, please consult the TEMPLATES file
located in the docs directory.
How do I install Devmon?
---------------------------------------
Detailed instructions are available in the docs/INSTALLATION
file. A single-node installation merely requires you to untar
the Devmon tarball to a suitable location, modify the config
file appropriately, and start the Devmon daemon.
A multi-node installation requires you to do all of the above
on each node in the cluster, as well as set up a MySQL database
to facilitate communication between nodes.
What are Devmon templates?
--------------------------------------
Devmon can monitor a virtually unlimited number of different
device types, by allowing a user to define a template for
each test to be conducted on a particular device type.
For instance, a 'cpu' test on a Cisco 2950 switch is its own
template, while a 'if_load' test on the same switch is an
entirely different template. A must read: the docs/TEMPLATES file!

Thanks for all the work done and also all patch/ideas submitted !
Special thanks to this fork version contributors
- W. Nelis
- Stef Coene
- Coec (Github name)
And all previous devmon admins and devs:
- Henrik Stoerner
- Steve Aiello
- Dan Vande More
- Craig Boyce
- Buchan Milne
This is a work in progress, changes can occur without notice ....
FEEDBACK ALWAYS APPRECIATED: use the github ISSUES to communicate even it is not a bug !
===========================================================================================================================================
Major changes after fork
. All patches from Sourceforge are integrated in this realease (some with adaptation)
- Improved User-Friendliness
- Add the 'Blue' color for test that are 'Disabled' and for fun !
- Error reporting
- Error propagation as "core" concept
- Multiple error messages and threshold for each oid color !
- New transforms:
- COLTRE : To collect data when there are "parent" oid values
- SORT : To sort in an increasing order (num or txt, default = txt)
oid values. The result (the new oid values) are
int indexes corresponding to the position of the source
oid values in the sort.
The results are a int between 1 and n
(n is the number of element in the branch oid)
It can be used to 'reindex' an oid if use in conjonction with
the CHAIN transform. (similar to the INDEX transform)
- SET : See the docs/TEMPLATE for explanation (Thanks to W. Nelis)
- STATISTIC : See the docs/TEMPLATE for explanation (Thanks to W. Nelis)

===========================================================================================================================================
TODO
Priority 1: Sourceforge open and bugs
Memory leaks
On linux (WIP)
On BSD (major)
One was in xymon-rrd, but should be fixed now? (version?)
Results: Minimized by fixing all errors: run devmon in foreground and show logs
SNMPv3: After triing to use the work from StefCoene, it seem more complicated that what I tought...
Document Transform Coltre, Sort
Ideas
Warn if autovivification (creates the hash if it do not exists, but it should not) and check if it does already make problem
Make Table compatible with LEAF
Share templates for similar devices: Lot of work!!!
Support for negative numbers in (T)SWITCH: Parse mathematical expression simply....: Need more work
Format display (SUBSTR negative, Align columns of a TABLE to the right side, Formatting of result of MATH transform): Problems Alignement and Padding
Exceptions based on other oid values: now only PriOi: make it work for alternate oid
Template exceptions sorted misleadingly: need documentation clarification
Use OID value in threshold comparison: Nice to have (workaround is to do that is transform)
FEATURE REQUEST
Better discovery (SF bug 10)
Multiple graph in a test
Add better timer calculation (HiRes)
HELP NEEDED
Template not listed above cannot be test: please help to updated: take a look at template liste above that are maintained!
Template exceptions sorted misleadingly: need documentation clarification: I dont used it: I need concrate case!)
