What's New in NSClient++ 0.5.2

Highlights:

• Brand new REST API
• Much improved documentation
• ZIP-Modules
• Op5Client

In addition to the above we have the usual slew of bug fixes and minor enhancements. One important change is that the code base have been re-factored in many places meaning the code will be easier to access for new developers. But more importantly this will allow for better unit testing in the future.

REST API

The new REST API is a true rest-full API which is not built around the internal protobuf API. This means it will be much simpler to work with and will allow you to much easier integrate it into your systems. The API also get support for uploading both scripts and modules to provide a truly remote configurable client. But the most important feature is access control on a per method level as well as user/password authentication. This means you can add a user which will only be allowed to run queries but not alter the configuration. We have also swapped out the old moongose implementation for one which is multi-threaded which means it will function a lot better under high load.

Documentation

Not only have we switched to a much easier to read template for the documentation we have added numerous pages about the REST API, Zip modules, Python script as well as much internal updates. In addition to this we have also reworked the reference section so it contains more useful information and less bloat.

Zip-modules

In brief zip-modules allow you to package scripts together as zip-files for easy distribution and use. With zip modules you can enable or disable all script in one go via the regular load/unload module concept.

Op5Client

A brand new Client which talk to Op5 natively via their northbound (Passive REST) API. The installer also has MSI options so you can silently install NSClient++ which automatically registers and becomes monitored from Op5.

msiexec /i NSClient++.msi OP5_SERVER=https://op5.com OP5_USER=monitor OP5_PASSWORD=rotinom

First 0.5.2 build which has a brand new web server. Please note this is very early in the web server development effort so there might be a lot of new bugs, and as always with front facing service bugs they might be remote exploitable... so use with care!

The mayor new benefit of the new web serve is that is is multi threaded meaning you can run any number of commands simultaneously.

• Fixed name of Windows 2016 server
• check_os_version: Added %(suite) to show wich suite is installed.

Major changes sine 0.5.0

The main goals of the 0.5.1 was to add event subsystem and make fix bugs/issues. In addition to this the installer has been rewritten as well as the documentation.

• Event subsystem
• New documentation
• New installer
• Numerous bugfixes and minor enhancements

Event subsystem

This is perhaps more interesting for developers of scripts for NSClient++ but it is a way to send notifications without having to adhere to the Nagios check result format. It was designed to make event-log to syslog forwarding simpler as well as detecting installed software and similar non check things. As of yet this can only be used inside internal scripts but the idea is to use these building-blocks to add many new features such as automatic monitoring configuration in the future.

New documentation

The old restructured documentation has been replaced with a new one based on mark down. This is actually more important then it seems as markdown renders on github this means you can now easily edit the documentation directly in your browser if you see any issues. The documentation was also brought back into the regular git repository as well making this even simpler.

New installer

While the installer is not all that new enough of the logic has been rewritten and tested to make sure silent installers are very very easy to make. Overriding configuration keys on command line is now much more predictable and works without strange voodoo.

Bugfixes enhancements

As always there are numerous bug fixes and enhancements and a full list of changes can be found in the documentation

• Added option to disable background checks in CheckSystem ((this is not useful as it breaks things, so only use if you have issues)

• Fixed #455 documentation about msiexec was wrong
• Fixed test mode crash
• Fixed check_service missing descriptions (#456)
• Fixed potential logger crash
• Added option to configure maintenance threads as well as changed metrics interval to every 10 seconds
