Measure, Alert on Ulimit level

Hi Tom, 

You could create a script datasource to get the ulimit value, here is an example below.  You would need to create a datapoint in the datasource using a key value pair *Key set to "Ulimit".  You can set a threshold in the datapoint for alerting.  You will need to set "ssh.user" and "ssh.pass" properties on the device.

The output from the script will look like this --> Ulimit:1024

/* Ulimit script */

import com.santaba.agent.groovyapi.expect.Expect

def hostname = hostProps.get("system.hostname");
def username = hostProps.get("ssh.user");
def pass = hostProps.get("ssh.pass");

// default timeout for Expect SSH
def timeout = 15;

// Command to get load average data
def ulimit_cmd = "ulimit -n\n";

// Expected shell prompt character, may have to be changed
// Linux generally uses "#" for root shells
def prompt = '\\$'

/*
 * Ulimit Pattern Key
 */
ulimit_pattern = ~/^(\d+)$/

// Connect to the device and wait for the prompt
ssh_conn = Expect.open(hostname, username, pass, timeout);
ssh_conn.expect(prompt);

// Send the ulimit command and wait for the prompt
ssh_conn.send(ulimit_cmd);
ssh_conn.expect(prompt);

// Iterate over output
ssh_conn.before().eachLine
{ line ->
//println line
    // Run the match
    matcher = ulimit_pattern.matcher(line);

    // Did we match?
    if (matcher.getCount() > 0)
    {
        // Yes, print data
        println "ulimit:" + matcher[0][1];
    }

}

// Exit the shell!
ssh_conn.send("exit\n");
ssh_conn.expectClose();

return 0;

Thanks for your time and effort on this :)/emoticons/smile@2x.png 2x" title=":)" width="20">
