Automatic Rule for process name in SNMP table

[dkoppenhagen]

Hey guys,

I am using the following rule automatic rule to add a template if a specific SNMP values has been found:

transport = CreateSNMPTransport($node);
if (transport == null) {
    return false;
}

value = SNMPGetValue(transport, ".1.3.6.1.2.1.25.4.1.0");
if (value == null) {
    return false;
}
else {
    return true;
}

This works so far pretty well.

But now I have some device where I want to check if specific processes are running on it.
I want to check via SNMP thecomplete hrSWRunTable (.1.3.6.1.2.1.25.4.2) if there is a process with a specific name (hrSWRunName has the OID .1.3.6.1.2.1.25.4.2.1.2).

So maybe I have to get all values form the tabel and then iterate over the entries and compare them. But I don't know how.

Do you have an idea how I should adjust my rule to find out if the process is running?
Maybe there is a better solution?

Btw: I am using NetXMS Version 2.0.7.

Thanks in advance guys.

Best regards,
Danny

Okay- I just solved my own problem.
In case somebody wants to do something similar (or maybe for the docs) here is how I solved this:

process = "My-Running-SW-In-The-hrSWRunTable.exe"; // defines process name for lookup

// Create SNMP transport for node
transport = CreateSNMPTransport($node);
if (transport == null) {
  return false;
}

// walk over running software processes
// .iso.org.dod.internet.mgmt.mib-2.host.hrSWRun.hrSWRunTable.hrSWRunEntry.hrSWRunName
vars = SNMPWalk(transport, ".1.3.6.1.2.1.25.4.2.1.2");
if (vars == null) {
  return false;
}

found_process = false; // set flag initially to false

// find process, set flag and break loop if process found
foreach (v: vars) {
  if(v->value == process) {
    trace(1, "SNMP WALK; Search for process: ".process."; Found: ".v->name."=".v->value);
    found_process = true;
    break;
  }
}

if (found_process == true) {
  return true; // process has been found
} else {
  return false; // process has not been found
}

Best regards,

Just one comment: code block

if (found_process == true) {
  return true; // process has been found
} else {
  return false; // process has not been found
}

could be replaced with simple

return found_process;
