A new nightly out. Nothing major just a few fixes to the CheckFile related module.

2009-02-26 MickeM
 * Changed fo missing files and such generate an error
 * Added option to return error messages to the client [CheckDisk] show_errors=1 (defauilt is off 0)
 * Added warning message ewhen numerical filters evaluate to zero (and are not 0)
 * Fixed major issue with date mathing in CheckFile* which was not working at all.

Note though that this new release is built with a new "kit" ie. new version of boost, openssl, and what not so things might be a bit more experimental then usual...

Hello,

I would like to welcome Opsera as a Gold sponsor for the NSClient++ project.

In other news I have been mad busy at work and with Windows 7 installes so nothing in the ways of updates. But hopefully after the weekend.

Also I can say: "Windows 7?" I actually dont get the hype. What is "new" it is pretty much like "XP" so in that regard it is a lot better then Vista (which I hated) but I cant really say there is much of a reason to upgrade from XP?

Most of the "addons" I already had in the form of third party products...

Well, we shall see, maybe it will grow on me?

(still havent installed a US enligh spellchecker in Firefox so excuse my spelling errors :)

I forgot to post that the nice people at netways have worked some magic which makes the site A LOT snappier!

The reason for the "slow down" is the 60+Gb/month traffic you all help generate. You can read some more on the netways blog over here http://blog.netways.de/2010/02/10/nsclient-plus-speed/.

Hello community!

Awesome to see someone actually helping out here :P Really really nice!

Also if there are any handy unix using people out there I will starting next week be doing a small (controlled) alpha of the up-coming 0.4.x branch which will (in addition to windows) also run on unix. The version is far from finished but it would be interesting to see how well it builds out there in the "big world" outside my Debian here at home.

The features currently supported in the 0.4.x branch is:

• NRPE Server
• NRPE Client
• NSCA Client
• Scheduler (NSCA does not have one anymore)
• Logging (to text file)
• CheckHelpers (simplest module)
• CheckExternalScripts

I would also really really like to get feedback on what people would like to see in the form of features and such. Especially on *nix where I am just now starting to thread lightly... Also feel free to let me know if I am stone crazy and should give upon this! :)

And again wicked big thanks to everyone who helps out and such on the forum/wiki/* here!!!

Hello,

I thought Id quickly post here that I will be in Warsaw (course about coherence) so probably wont be much updates this week. If anyone has any sightseeing ideas or wanna grab a beer or something like that drop me an email at michael at medin dot name.

As for the client there is a new nightly build out a few days ago with some fixes and such. I am currently reworking some stuff in the 0.4.x brance wich I hope to have a beta for in the next few weeks.

Again more improvements and changes to the disk related checks.

Highlights are:

• Better performance data for CheckDrive? (now always shows absolute sizes) so you can plot better graphs.
• Volume support for CheckDriveSize (CheckAll?=volumes)
• User support in syntax for CheckEventLog
• Support for "future dates"

Now is a very good time to submit all feature requests for disk related checks as I am working over those parts.

Full changlog

2009-12-31 MickeM
 * Fixed CheckFile* time handling so it is "signed"
   This means you can check for "future dates" as well as future dates works correctly:
   Like so:
    CheckFile2 debug path=D:\tmp\dates filter+creation=>30m MaxWarn=1 MaxCrit=1 "syntax=%filename%: %creation%"
    CRITICAL:past.txt: Thursday, December 31, 2009 08:47:30, found files: 1 > critical|'found files'=1;1;1;
    CheckFile2 debug path=D:\tmp\dates filter+creation=<-30m MaxWarn=1 MaxCrit=1 "syntax=%filename%: %creation%"
    CRITICAL:future.txt: C: Thursday, December 31, 2009 12:47:11, found files: 1 > critical|'found files'=1;1;1;
 + Added volume support for CheckDriveSize (CHeckAll) like so:
   Like so:
    CheckDriveSize MinWarn=50% MinCrit=25% CheckAll=volumes FilterType=FIXED FilterType=REMOTE
 + Added %user% to syntax to print user who generated message.
   Like so:
    CheckEventLog file=application file=system filter=new filter=out MaxWarn=1 MaxCrit=1 filter-generated=>2w filter-severity==success filter-severity==informational truncate=1023 unique descriptions "syntax=%user% (%count%)"
    CRITICAL: (1),  (2), NT INSTANS\SYSTEM (3), NT INSTANS\SYSTEM (3), NT INSTANS\SYSTEM (3), missing (3), missing (5),  (4), missing (2), missing (2), missing (2), missing (2),  (1), eventlog: 33 > critical|'eventlog'=33;1;1;

2009-12-21 MickeM
 ! BREAKING CHANGE!
 ! New perfoamcen data syntax for ALL % checks
   Alias is '<alias> %' and it also has the "full" non % data as '<alias>'
   Like so:
	CheckDriveSize CheckAll MaxWarnUsed=80% MaxCritUsed=90%
	CRITICAL:CRITICAL: C:\: Total: 146G - Used: 140G (95%) - Free: 6.31G (5%) > critical, D:\: Total: 152G - Used: 148G (97%) - Free: 3.59G (3%) > critical|'C:\ %'=95%;80;90; 'C:\'=140.17G;117.18;131.83;0;146.48; 'D:\ %'=97%;80;90; 'D:\'=147.93G;121.21;136.3;0;151.52;

Mainly disk and file related additions:

• New command: CheckSingleFile?
• A few new options for CheckFile2

Full changelog here

2009-12-13 MickeM
 + Added new command: CheckSingleFile to check aspects of a single file use like so:
   CheckSingleFile file=d:\nrpe_512.pem warn=>100 check=line-count warn=>100 crit=>170 check=size
 + Added option debug to CheckFile2 to enable printing of debug information
 + Added ignore-errors to "ignore" any filesystem related errors (NOTICE this is probably not what you want)
 + Added master-syntax to CheckFile2 to change the overall message like so:
    It takes three options (and char data):
     * %list% A list of all "files" (syntax controls this)
     * %files% number of files
     * %matches% number of files matched
    CheckFile2 MinWarn=10 MinCrit=10 path=D:\WINDOWS\system32 filter+size=gt:0 truncate=10 ignore-errors "master-syntax=%matches%/%files%"
    OK:7177/7...|'found files'=7177;10;10;

2009-12-06 MickeM
 + Added != to all string filters
 + Sorted out the alias handling it is now wither what you specify or "files found" (this makes performance data work)
 + Added version to CheckFile2
   CheckFile2 path=D:\tmp pattern=*.exe filter+version=!=1.0 "syntax=%filename%: %version%" MaxWarn=1
   CheckFile2 path=D:\tmp pattern=*.exe filter+version=!=6.0.2900.5512 "syntax=%filename%: %version%" MaxWarn=1
 + Added line count to CheckFile2 to count lines
   CheckFile2 path=D:\tmp pattern=*.txt filter+line-count=!=2 "syntax=%filename%: %line-count%" MaxWarn=1
   CheckFile2 path=D:\tmp pattern=*.txt filter+line-count=ne:3 "syntax=%filename%: %line-count%" MaxWarn=1

New version out mainly a fix for the problems of 0.3.6 version.

Major changes:

 * Added argument support to NRPE Client
 * Some additions and fixes CheckWMI
 * Improved installer (works on w2k8 etc)
 * NSCA feature and stability improvments
 * New command line switchs to easily use NSClient++ from external scripts
 * Added "firewall exception" to installer
 * Fixed an issue with the socket data buffer
 * Fixed issue with CheckExternalScripts and script_dir
 * Fixed issue with CheckDisk and paths
 * Documentation!

I think the major thing is the documentation apart from some bug fixes and installer improvements such. Regardless it is a recommended update.

NOTE It is late so I shall update sourceforge and what not tomorrow.

// Michael Medin

Hello,

Sorry everyone for the downtime but apparently a hardware failure occurred, everything is back up and running now again and I think given the situation this spring it is a huge improvement! Especially since this is the first downtime in months!

UPDATE No planned downtime tomorrow! Just got a quick shout from Bernt Erk at netways that they wont have to move the host tomorrow so no planned downtime for tomorrow.

So once again a big thank you to the people at netways awesome hosting!

// Michael Medin

New nightly build out. Mainly this has a much improved installer so please let me know how it work out.

Also if you have an old version of NSCLient++ (which is not upgraded/uninstalled propperly) send mt the install log (msiexec /l* log.txt /i <MSI>) so I can add it to the "uniinstall thingy" I have added.

There is also some fixes in the CheckFile department which fixes a few issues here and there.

// Michael Medin

Hello everyone (yes, I know.. no one reads this but anyways feels better pretending not talk to myself)...

I have added a new guide (it I hope illustrates the basics of using NSClient++ with Nagios) on how to check if a process is running on a windows machine. It draws upon the earlier guides I published recently and tries to be very through and detailed. Please let me know if they are helpful or not and how I can improve them. The guide ca be found here or from the new Check Guides Page.

I have also reworked the "menu system" for the wiki to something slightly more "compact" and hopefully easier to work with, please let me know what you think.

Old	New

Also don't forget the Netways Conferance this fall:

I will also give a presentation on Application Monitoring where I will dive into how to monitor your Java based middleware via (amongst other things) JMX.

Details on the conference can be found at the web page http://www.netways.de/en/osmc/y2009/splitpage/.

Netways will be holding an Open Source Monitoring Conference with a strong focus on Nagios again this year. I shall (again) be speaking and this year. Last year I did a presentation on Windows monitoring and I will follow up that this year with a workshop. The topic for the workshop will focus around windows monitoring and we will install/configure NSClient++ and then setup a series of checks to monitor your windows environment.

In Addition to this I will also give a presentation on Application Monitoring where I will dive into how to monitor your Java based middleware via (amongst other things) JMX.

Details on the conference can be found at the web page http://www.netways.de/en/osmc/y2009/splitpage/.

Feel free to hit me with questions before and I shall try to incorporate the answers in my presentation. Also if you attended last year feel free to provide me with some feedback so I might improve this years presentation!

// Michael Medin

Hello everyone.

I have some really nice news and lets get started by a big big thank you to the guys over at netways in Germany for hosting the site. It is an amazing performance improvement!

Secondly to start off the summer I have written a guide on how to use NSClient++ with Nagios (NSClient, NRPE and NSCA) it is brand new and feedback is appreciated!

The guide can be found on the wiki as well as a PDF (attached below). The idea is to distribute the PDF with the installation package as the first step in improving the documentation of NSClient++.

Next up is 0.3.7 build which will fix a few issues and (if I have time) add some new stuff. I shall also go over the wiki and try to update the documentation but it is lengthy and (perhaps more so) boring work.

As always if anyone wants to donate to the project and help keep up my documentation spirit feel free to visit the donation page and become a "fan" of NSClient++. Donations are always welcome!.

And finally another big shout out to the guy at netways!

Finally after and long overdue is the new version here. This is a major update and a recommended one as there are memory leaks in the previous version.

The highlight in addition to all the fixes and minor things are the experimental new installer which allows you to configure some options while installing NSClient++. The installer should I hope work better and provide easier error handling and such. The only issue thus far are some reports on windows 2007 where it requires administrative privileges to install. I do not have windows 2007 so I cannot confirm this (if someone has windows a spare 2007 or want to sponsor this platform get in touch with me).

A few of the highlights:

 * Improved installer
 * A lot of bugfixes and improvements 
 * Serious memory leak fixed
 * Added a few new options to NSCA module
 * New service name and description
 * Improved CHeckFile2 (new option max-dir-depth, path, pattern)
 * Added support for changing name and description of service from the /install
   command line
 * Added more filter operators to all numeric filters so they accept 
   eq:, ne:, gt:, lt: in addition to =, >, <, <>, !, !=, in: (#269)
 * Added better support for numerical hit matching in the eventlog module. 
   You can now use exact and detailed matching.
 * Cleaned up the checkProcState code and it is not a lot better.
 * Added new option 16bit to checkProcState. 
   When set checkProcState will enumerate all 16 bit processes found running under NTVDM.
 * Added new command line options pdhlookup and pdhmatch (to CheckSystem) to 
   lookup index and names.
 * Added new module A_DebugLogMetrics.dll which can be used to generate debug info.
 * Brand new build environment based upon boost build!!!
 * Modified /about so it now shows a lot of useful(?) info.

For all changes refer to the changelog.

On a side not I will during the night switch over to a new host so hopefully the site will be more stable as well!

// Michael Medin

Not much news in this build which contains a bunch of bug-fixes as well as a compleate version of the new installer.

• CheckFileAge? (was broken)
• NSCA config option time_delay was off by 1000.
• Eventlog monitoring with descriptions flag was crashing on x64.
• CheckProc? works better on x64
• New installer is "finalized"

The RC is called X this time as I did not want to rename all the others. If no one reports in bugs this will become 0.3.6 release in 24 hours or so.

Full change log:

2009-06-07 MickeM 
 * Fixed issue with CheckFileAge incorrectly working in recursive mode.
 * Finalized the installer

2009-05-22 MickeM 
 * Fixed time_delay option in NSCA config (now uses the correct base was 1000 times to large before)

2009-05-21 MickeM 
 * Fixed issue with eventlog parsing and 64 bit machines (descriptions option)
 * Fixed issue with "modern windows" and installing the service (should not have the correct privlaiges)

2009-05-17 MickeM 
 * Changed default buffer size for process enumeration (64K now instead of 1K should I hope work better on 64bit OS:es)

2009-05-10 MickeM 
 + Added write support for modules to installer

// Michael Medin

Hello,

Since the presentation I did on Noric Meet on Nagios is on bambuser I figured I would share the link to it so you might all enjoy :)

Topics are:

• Basic Usage of NSClient++
• Basic Monitoring features
• Eventlog monitoring
• WMI
• Scripting (very briefly)

For the presentation go here.

I also held a workshop on scripting on the "windows side" which unfortunately was not filmed. But I shall add the slides and material to the wiki this weekend.

// Michael Medin

Just saw that there are live feeds from the Nordic Meet on Nagios avalible here in about an hour or so I will give my presentation on windows monitoring.

// MickeM

Because I got a request (Elad Shapira) as well as a recommendation for a tool (wink) I decided to try it out:

This is a short and quick webcast (demo?) on starting NSClient++ in debug mode and stopping it and how to intercept calls from nagios and see what happends in real time. This is just a quick thing to try it out let me know how what you think...

// Michael Medin

Hello,

Since spam is picking up I have, again, disabled anonymous posting to see if this helps a bit. It is op to post just register a user (capta) and you should be fine. If anyone has problems with this let me know at michael<at>medin<dot>name
