OMW: Script to Change Agent from DCE to HTTPs Part2

Many administrators looking to automate the time consuming process, I had seen requests in HP support forums on how to change agent in bulk

I have created the below script which utilizes Policy Management and Deployment (PMAD) API which mainly starts by

set pmad = CreateObject("PMAD.OvPmdPolicyManager") 
pmad.ConnectDB


We can compare the above lines by opening the Node Editor


Set node = PMAD.CreateNode(nodeGuid)


The line above is locating or creating a node typically like Selecting the node you will modify the agent attributes.


createnode = node.ChangeAgent(liAgentCommType,wminode.AgentBinaryFormatId,256, "", "")


The lines above is like right click the node and select Change Agent which is executed by ChangeAgent() function which should be formatted like ChangeAgent(lAgtType,lBinaryFormat,ulOptions,sUser,sPwd)


lAgtType
- Defines the communication type of the HP Operations agent (DCE or HTTPS) that should run on the node.

lBinaryFormat
- Defines the binary format of the HP Operations agent that should run on the node.

ulOptions
- Defines the type of authentication that will be used for the operation



  • PMAD_DEPL_NONE_OPT - This flag cannot be combined with any other flags. Use this flag when you do not want to pass any other flags.
  • PMAD_DEPL_IGNORE_OWNER_OPT - If this flag is NOT SET, the operation fails if some policies are owned by another management server. If this flag if SET, the owner attribute of the policies is ignored.
  • PMAD_DEPL_FORCE_OPT - If this flag is NOT SET, the operation fails whenever there are policies in the inventory on the server for which no data is available. However, if this flag is SET, policies with no data are ignored (that is, not deployed again).
  • PMAD_DEPL_IMPERSONATE_OPT - If SET, the remote managed node is accessed with the security context of the impersonated user (the user that called this API).
  • PMAD_DEPL_PMADUSER_OPT - If SET, the remote managed node is accessed with the security context of the HP-OVE-Deleg-User account (the one under which PMAD is running).

Which I chose PMAD_DEPL_IMPERSONATE_OPT which uses the current user this options has a hex value 0x100 and the ulOptions means unsigned long which means a non negative decimal value which means here 256


sUser
- Name of the account used to access the remote node. You can specify the account either as a user principal name (UPN such as UserName@DomainName) or in the down-level log-on name format (DomainName\UserName).
sPwd
- Password of the account used to access the remote node.

OMW: Script to Change Agent from DCE to HTTPs Part1

HP Operations manager prior to version 8, managed node are monitored through Agent uses RPC/DCE communication, which had lots of issues as it is unsecured communication and communication configuration headache for the Agent and Server through firewall

In HP Operations Manager 8  and later a new Agent is introduced called HTTP agent which uses encrypted HTTPs certificate-based communication to secure the data and uses only single port for the communication between OM and Agents ( TCP 383 by default)

So organizations with DCE Agents should be change the agent to HTTPS based to leverage the new features. the process is quite simple as the Administrator should access the Node Editor and Change the agent

To change the agent type

Open Node Editor by Right click Server Node > Configure > Node

Select Node and right click select Change Agent

image

This process will performs deployment operation as the following steps:

  1. Removes all packages and policies that are currently installed on the node.
  2. Deletes the server inventory for packages for the specified node, but keeps the server inventory for policies.
  3. Changes the agent type, binary format, or both of the node in WMI.
  4. Deploys the new binary of the HP Operation agent to the node.
  5. Redeploys all policies that were previously installed on the node (they are still in the server inventory) to the node. The additional agent packages and the instrumentation that is required by these policies are automatically deployed first.

OMW:Read Multi-lined log files

I had seen so many questions about joining multiline log  as in OMW the Log Interceptor is parsing line by line, so if your data is scattered on different lines it can not be monitoring unless you imply a pre-processing script.

 

I have created the below script is to join multiple lines together but if match a certain keyword

If Wscript.Arguments.Count < 2 Then
wscript.echo "Usage cscript joinlines.vbs ""logfilepath"" ""machingtext"" "
wscript.echo "Ex:"
wscript.echo "cscript joinlines.vbs ""d:\logs\filename.log"" logfilename "
Else
Set args = WScript.Arguments
arg1 = WScript.Arguments.Item(0)
match = WScript.Arguments.Item(1)
Set fsObject = CreateObject("Scripting.FileSystemObject")
nodesFile = arg1
Set file = fsObject.GetFile(nodesFile)
Set line = file.OpenAsTextStream(1,TristateUseDefault)
dim arrFileLines()

Do Until line.AtEndOfStream
Redim Preserve arrFileLines(l)
arrFileLines(l) = line.ReadLine
l = l + 1
Loop
For l = Ubound(arrFileLines) to LBound(arrFileLines) Step -1
If Instr(arrFileLines(l), match) > 0 then
wscript.echo "maching line " & arrFileLines(l-1) &" " & arrFileLines(l)
end if
Next

End if


Save the contents to joinlines.vbs


It can be implemented in different ways:


You can create a log file policy to search for your error message in each line as the sample below


20110326 08:00:13 expdp_SHARED_DATASTAGE.sql started ok
20110326 08:14:13 expdp_SHARED_DATASTAGE.sql completed ok with this output:
The job "EXPDP_USER". "SYS_EXPORT_SCHEMA_06" failed at 08:15:00: ERROR
20110327 08:00:13 expdp_SHARED_DATASTAGE2.sql started ok
20110327 08:14:13 expdp_SHARED_DATASTAGE2.sql completed ok with this output:
The job "EXPDP_USER2". "SYS_EXPORT_SCHEMA_02" failed at 08:15:00: ERROR
20110328 08:00:13 expdp_SHARED_DATASTAGE3.sql started ok
20110328 08:14:13 expdp_SHARED_DATASTAGE3.sql completed ok with this output:
The job "EXPDP_USER2". "SYS_EXPORT_SCHEMA_03" failed at 08:15:00: ERROR


1- You may create your rule to search for the word error and to send message and we can use the script as automatic action to get the previous lines and to append it to the annotation

2-You can create the policy to pre-process the log  and write the output to a text file to be read.


cscript /nologo log.vbs backup.log ERROR >c:\windows\temp\joinedlines.txt

OMW: Log file monitor for multiple log files

To monitor multiple files using a OMW log file monitor policy, you have to configure the policy to list those files separated by spaces.

Normally in Unix-based systems if you used ls command with wildcards, the result will be the full files path and separated by spaces

In Windows, dir is not delivering the same result as

if you try dir /b /s it will show each file in separate line

image

if you used /w command it display the files without path, so I created the below script to list the files with /w and add the path to the output

If Wscript.Arguments.Count < 2 Then
wscript.echo "Usage cscript listlogs.vbs ""directry"" filename "
wscript.echo "Ex:"
wscript.echo "cscript listlogs.vbs ""d:\logs\"" logfilename "
Else
directory = WScript.Arguments.Item(0)
fileName= WScript.Arguments.Item(1)
Set objShell = WScript.CreateObject("WScript.Shell")
command = "cmd /c dir /l /w " & directory & "*" &filename & "*.log"
Set oExec = objShell.Exec(Command)
Do While Not oExec.StdOut.AtEndOfStream
commandoutput = oExec.StdOut.ReadLine()
If Instr(commandoutput, ".log") > 0 then
replaced = replace(commandOutput,filename, directory & filename)
wscript.echo replaced
End if
Loop
End if


The next step is to deploy this script to your Managed Nodes, we may create new Instrumentation by creating a new folder under %ovdatadir%\shared\Instrumentation\Categories ,  lets name it LogFileMonitor


image


Browse to the Policy Group or to Policy Management –> Policies grouped by type-> Agent Policies –> Logfile Entry


image


In the Log file path type <`c:\windows\system32\cscript.exe /nolog listlog.vbs c:\Cisco\log\ cisco`>  but during the test it work with me as <`c:\windows\system32\cscript.exe /nologo "%ovdatadir%"\bin\instrumentation\listlogs.vbs c:\Cisco\log\ cisco`>


image


Save the policy, you may use Category option to automatically deploy the instrumentation with the policy (requires certain configuration)


image









Distribute the instrumentation,then deploy the policy to your managed nodes.

OMW: List log files to be monitored

 

In an answer to HP support forum about how to list files with certain extention to be used on OMW

We have a sample directory contain may different logs, we need to monitor only files start with cisco

image

Use dir /b /s will list the files only with their full path

image

to optimality integrate this with OMW

Create a log file monitor and under file to be executed type <`cmd.exe /c dir d:\cisco\log\cisco*.log /b /S`>

This will enabled the logfile policy to read all the files and will parse them for the policy rules

This was in respond to Logfile Monitoring with File name changes after server reeboot

OMW: Alert when files are older than 30 minutes Part 1

1- Create the needed script

This script is listing the files that are located in certain directory

cscript /nologo checkolderfiles.vbs abc c:\scripts list

I have added two features for the script

One is to display list the files which are not modified within the time specified

file1.txt
file2.txt
listfiles.vbs


Second is to use opcmon to with a count of files that are not modified before 30 minutes


cscript /nologo checkolderfiles.vbs abc c:\scripts alert

2-prepare the file for distribution


Create a folder name it filesmonitoring under <ovdatadir>\shared\Instrumentation\Categories


image


3-Create Measurement Threshold Monitoring Policy


Create Measurement Threshold Policy name it “monitoroldfiles”


Use Source Type as Program


type in the command area


cscript /nologo checkoldfiles.vbs abc c:\scripts alert

this to run the script to check for the files located in c:\scripts and will generate alert with opcmon policyname=<number of files>


Create a matching rule to send alert if the value is greater than 0 to match the value sent by opcmon  and generate the alert


Add automatic command to this alert to list down which policies are not changed within the time assigned.


The command should be


cscript /nologo checkoldfiles.vbs abc c:\scripts list

4-Deploy the the instrumentation for filemonitoring to the nodes where this policy will be used.


the full script is below and name it checkoldfiles.vbs


nodeName = "."
If Wscript.Arguments.Count <; 3 Then
wscript.echo "Usage cscript checkoldfiles.vbs ""PolicyName"" ""<Files direcotory>"" ""<Alert |List >"" "
wscript.echo "Ex: to send the count to the OM"
wscript.echo "cscript listfiles.vbs abc c:\scripts alert"
wscript.echo "Ex: to list the files"
wscript.echo "cscript listfiles.vbs abc c:\scripts list"
Else
policyname = WScript.Arguments.Item(0)
path= WScript.Arguments.Item(1)
action=WScript.Arguments.Item(2)

myPath = Split(path,":")
drive= myPath(0)
if right(myPath(1),1) <;> "\" then
directory = replace(myPath(1),"\","\\") &; "\\"
else
directory = replace(myPath(1),"\","\\")
end if
Set dateTime = CreateObject("WbemScripting.SWbemDateTime")
dateTime.SetVarDate( DateAdd("n",-5,now()))
Set objWMIService = GetObject("winmgmts:" _
&; "{impersonationLevel=impersonate}!\\" & nodeName & "\root\cimv2")
query = "Select * From CIM_DataFile Where Drive = '"&; drive &":' and Path = '"& directory &"' and LastModified < '" & dateTime.Value &"'"
Set colFiles = _
objWMIService.ExecQuery(query)
if action= "list" then
listfiles()
elseif action="alert" then
alert()
end if
end if
Function listfiles()
For Each objFile in colFiles
strNewFile = objFile.FileName &; "." & objFile.Extension
Wscript.Echo strNewFile
next
End function
function alert()
Set objShell = WScript.CreateObject("WScript.Shell")
command = "cmd /c ""%ovinstalldir%\bin\opcmon.exe"" " &; policyname & "=" & colFiles.Count
Wscript.Echo command
Set oExec = objShell.Exec(Command)
Wscript.Echo "The output of the command: " &; Command
Do While Not oExec.StdOut.AtEndOfStream
commandoutput = oExec.StdOut.ReadLine()
Wscript.Echo commandOutput
Loop
end function
