I need some help with Nagios monitoring.
I installed on server and agents but when I go to main screen I see only two services being monitored and what is says is that two services in "Critical"
I have attached screenshots for the same but what is says is the below two services monitored on agents ?? I thought they should be eight ?
Current Users
CPU Load
The following services are critical with command not found error:
SH Monitoring -- NRPE: Command 'check_ssh' not defined
FTP Monitoring-- NRPE: Command 'check_ftp' not defined
Any help would be greatly appreciated.
Check ssh and check ftp are external commands so I had to delete check_nrpe| from client side to make it work. Secondly I had to also install FTP Server for FTP monitoring to work. All good now.

I wonder if we can start or stop a website on IIS-8.5 running on a remote server which is on a different domain (I can provide the credentials if needed in batch file).
I know if it is a local site running on our machine we can use batch file like,
#echo off
appcmd start sites "local.xyz.com"
pause
I appreciate your help on this.
Thanks in advance.
Several options. I just list two below,
If you can use PowerShell remoting, then you can easily access appcmd or equivalent commands on the remote machine.
If you can deploy IIS Administration API, you get even more possibilities.
I am trying to sftp(SSH) transfer files from a remote server to a local directory in SSIS. I was recommended to use PSFTP.exe to conduct the transfer via a batch file. In debug mode, this works flawlessly, but when deployed to SSIS Catalog, the job stalls at the point to connect and transfer the files. I have no errors from SSIS. The job just freezes. The user set in the job is in the administrator's group. I am missing something. How do I troubleshoot?
Thank you.
Thanks to #Nick.McDermaid, I found out that adding the flag -batch and the key -hostkey aa:bb:cc:........ fixed my problem. for some reason, even though i have the RSA key approved via CMD line, the ssis package did not see the approval, forcing the acceptance. adding the hostkey flag solved the key issue, and the batch flag turned off the interactive setting.
I'm writing a perl script in which I've to shutdown my mssql server ,do some operation and then I've to restart it.I know 1 way is to use netstat to stopt the service but I cann't use that. So I tried installing DBI and DBD::ODBC module.
More info here :Shutdown MSSQL server from perl script DBI
But when I trying to shutdown my server using this command
$dbh->prepare("SHUTDOWN WITH NOWAIT ");
It's not working for me :
I got this response from the community
SHUTDOWN permissions are assigned to members of the sysadmin and serveradmin fixed server roles, and they are not transferable. I'd consider it unlike(hopefully) that perl is run with this rights.
So please tell me is there a way to run the above command as these users ? or what can I do other than this . Note that I have a constraint tha tI cann't simply stop it as windows service.
If the scripts are executed through a web browser then the user executing the scripts will be defined by the web server. It will probably not be a good idea to fiddle with this user. Just leave things as they are.
What you can do is to create a Perl script that is being run by a privileged user on a consistent basis with CRON.
This script being run by CRON can check for specific content like a file which has been written by a script where the user executing the script has lesser privileges.
So the way it could work is as follows:
You execute browser.cgi through a browser to do a specific task.
browser.cgi writes instructions to a file.
Every 1 minute priveleged.cgi executes via CRON. (The root user could execute priveleged.cgi)
priveleged.cgi reads the file browser.cgi has written for instructions and starts and stops services according to the instructions.
I want to copy some files from a network shared drive (mounted at my local machine as drive Z). I have written a Batch file to copy the contents of Z drive into my local drive. This batch file runs successfully on cmd, but i am having issue when i trigger it through Jenkins. The Jenkins gives the following error:
"The system cannot find the specified drive"
Any help regarding this, will be greatly appreciated.
Thanks,
Nouman.
If you don't want to use Jenkins-plugins or schedule-Tasks here is a "groovy" way:
By Hand:
You can use the Groovy Script-Console provided by Jenkins>Manage Jenkins>Script Console and execute the command to map the network-drive within the Jenkins-service. (Must be repeated, once the Jenkins-service is stopped)
Automation:
Write your Groovy commands to a file named "init.groovy" and place it in your JENKINS_HOME-directory. So the network-drive gets mapped on Jenkins-startup.
Groovy Commands - Windows:
Check available network drives using the Script-Console:
println "net use".execute().getText()
Your init.groovy would look like this:
def mapdrive = "net use z: \\\\YOUR_REMOTE_MACHINE\\SHARED_FOLDERNAME"
mapdrive.execute()
Yes Jenkins uses different login credentials. To map a drives through Jenkins use below command in Jenkins command prompt:
Subst U: \drive\folder
then after that your queries.
You might run into permission issues. Jenkins might be executed with different user credentials; so it does not know the configured drive for the windows share. Instead of using shell scripts I suggest to use a plugin. There is a set of Publish-over plugins that allow deployments to remote systems via a couple of protocols (ssh, cfis etc). Have a look at the CFIS plugin that allows to send artifacts to a windows share. Once the plugin is configured (ie the host is specified in the Manage Jenkins section) you can add to the post build steps Send files to a windows share where you can specify which file(s) shall be sent to which location.
Had this issue where my jenkins job was unable to read files present on the network drive.
I resolved it by adding "net use" command in your pre-build step. i.e.
Open your job.
Go to Pre Steps
From the drop down, select Execute Windows Batch Command
Enter the following command:
net use E: \[server name][Folder name] "[password]" /user:"[userid]"
Click Save
Execute the job
I was able to read files from my network drive by following the steps mentioned above.
It seemed to be a one time activity as after the initial run, I had removed the batch command from my job and it seemed to remember the mapped drive command.
Try adding debugging commands to that bat file, or as separate build step, such as net use, set (pay attention to vars like like HOMEPATH and USERNAME) and plain dir Z:\.
As said in another answer, most likely reason is that Jenkins runs as SYSTEM user, which has different permissions. One way around that is, go to services (for example open Task Manager, go to Services tab in it, click the Services button at the lower right corner of that tab), find Jenkins service, open it's properties, go to "Log on" tab and set your normal user account as one that runs Jenkins.
Basically you can access your network shared drive (Z) using by servername or IP from jenkins command. Write \\192.168.x.xxx\Your_Folder instead of z:\Your_Folder.
For example:
mkdir \\192.168.x.xxx\Your_Folder
I was trying to copy files from one remote computer to other, the easy solution which worked for me is COPY iphone.exe \192.xx.xx.xx\dev(dev is the folder name on c drive in that ip address)
A similar issue showed up for us on Jenkins slaves set up on Windows Server 2008 following this documentation. The Jenkins agent failed to access the mounted network drives even after configuring the agent service with the correct user credentials.
Troubleshooting:
Jenkins could access the mounted network drives by their drive letters when connected via the JNLP agent (Launch agent via Java Web Start).
It stops recognizing the drive letters soon after we install the agent as a Windows service. Configuring the correct user credentials and restarting the agent does not help.
We could still access the drives via the command line while logged in to the machine with the above user.
Stop the agent service from services.msc and then uninstall it by running the command jenkins-slave.exe uninstall. The slave is disconnected at this point.
Reconnect the slave by launching the JNLP agent via Java Web Start. The agent can now access the network drives again.
Synopsis:
Do not install the slave agent as a Windows service to keep accessing your mounted network drives using drive letters. But this is highly unreliable as the agent might fail to restart after a machine reboot. Alternatively, see if Jenkins can access them via \\<ip_address\of\network\drive>.
In order to access your remote drive
just use the command in cmd prompt
pushd "\sharedDrive\Folder1\DestinationFolder"
mkdir FolderName
popd
pushd >> It navigates to the shared drive by creating a virtual drive..
popd >> Gets you back to the local directory
What is the simplest way to schedule a batch file to run on a remote machine using Hudson (latest and greatest version)? I was exploring the master slave setup. I created a dumb slave but I am not sure what the parameters should be so that I can trigger the batch file in the remote slave machine.
Basically, I am trying to run 2 different batch files on two different remote machines sequentially, triggered from my machine (the master). The Step by step guide on the Hudson website is a dead link. There are similar questions posted on SO but it does not quite work for me when I use the parameters they mention.
If anyone has done something similar please suggest ways to make this work.
(I know how to set up jobs, and add a step to run a batch file etc what I am having trouble configuring is doing this on a remote machine using hudson in built features)
UPDATE
Thank you all for the suggestions. Quick update on this:
What I wanted to get done is partially working, below are the steps followed to get to it -
Created new Node from Manage Nodes -> New Node -> set # of Executors as 1, Remote FS root set as '/var/hudson', set Launch method as using JNLP, set slavename and saved.
Once slave was set up (from master machine), I logged into the Slave physical machine, I downloaded the _slave.jar from http://masterserver:port/jnlpJars/slave.jar, and ran the following from command line at the download location -> java -jar _slave.jar -jnlpUrl http://masterserver:port/computer/slavename/slave-agent.jnlp. The connection was made successfully.
Checked 'Restrict where this project can be run' in the Master job configuration, and set paramater as slavename.
Checked "Add Build Step" for adding my batch job script
What I am still missing now is a way to connect to 2 slaves from one job in sequence, is that possible?
It is fairly easy and straight forward. Lets assume you already have a slave running. Then you configure the job as if you are locally on the target box. The setting for Restrict where this project can be run needs to be the node that you want to on. This is all for the job configuration.
For the slave configuration read the following pages.
Installing Hudson as a Windows service
Distributed builds
On windows I prefer to run the slave as a service and let the remote machine manage the start up and shut down of the slave. The only disadvantage with this is, you need to upgrade the client every time you update the server Just get the new client.jar from the server, after the upgrade and put it on the slave. Then restart the slave and you are done.
I had troubles using the install as a service option for the slave even though I did it as a local administrator. I used then srvany to wrap the jar into a service. Here is a blog about it. The command that you need to wrap, you will get from your Hudson server from the slave page. For all of this to work, you should set up the slave management as jnlp.
If you have an ssh server on your target machine, you can use the ssl slave settings. These work for me like a charm. I use them with my unix slaves. So far the ssl option with unix is less of an hassle, than the windows service clients.
I had some similar trouble with slave setup and wrote up this blog post - I was running on Linux rather than Windows, but hopefully this will help.
I dont know about how to use built-in hudson features for this job - but in one of my project builds, i run a batch file that in turn uses PSTools
to run the job on a remote server. I found PS tools extremely easy to use - download, unpack and run the command with the right parameters, hence opted to use this.
