Need help on running combination of Nagios, Nconf, and Nagiosgraph on Linux

1sysadmin — Thu, 14 Oct 2010 14:49:04 +0000

Hi, I am new to Nagios and I am having problem to put all this applications together. I have very limited knowledge of all this tools and availability, so I need experts help on this. Here are the steps that I went thru: I installed Nagios in one of my Linux server. In the same machine but different directory I Installed Nconf to add about 70 hosts with about five services for each hosts. I have to add about 200 more hosts. I used CSV (comma-separated values) file to store the data. Now, I need graph so I installed Nagiosgraph and I am trying to make it work since last two weeks, but it is not working. When I reload nagios, it runs fine and I see the icon to brows to the graph, but when I click on it, I get following error: (Server error! The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there was an error in a CGI script. ) If you think I didn’t select right tool to add hosts and for graph, what is better tools to add bunch of servers and to get the graphs. I also have some switches to monitor too. Thanks

Hi,

Its about writing 2 command line argument.First argument i have created a file and put some text to it before writing the script.

But i got stuck with second argument its an integer.The script should echo to the standard out put – the message”FILE IS SHORTER”.

If the number lines in the file named in the first argument is less than the integer the value of second argument should show echo to the standard”FILE IS NOT SHORTER”.

Linux stdout redirection to file contains “@” and stops redirecting

Cejennings — Wed, 08 Jul 2009 14:25:57 +0000

Hello Experts,

I have a tcl/expect script that I am performing “log_user 1″ to capture all the output from the script. I am performing the standard redirect and when I perform an exp_send comand with an “@” in the line, my stdout redirection stops. The tcl/expect script continues with no problem – but the output I am looking for is not there:

./expect_script.tcl >> stdout.log 2>> stdout.err

inside the expect script where the stdout redirection stops:

 exp_send -s "no snmp-server community 3x@mp!3 RO 88\r

Thanks.
