Is there any plan to offer pre-built sensors to monitor EMC San? (Clariion/VNX platform) Or is there another method?

Hi folks,

As there is no or very poor monitoring tools for the EMC storage, I have implemented a solution to check hardware failure and integrity of the disks

  • I have 2 VNX 5100 SAN storage
  • I have 1 AX4 SAN storage

Both hardware works the same manner

First, you have to download from your EMC account, the CLI tools, which is called "NaviSecCLI". Then, install this package in your PRTG server under "C:\program files (x86)\PRTG Network Monitor\Custom Sensors\EXE.. If you don't have an account by EMC to download the software, ask your resealer.

Second, you have to write a small script (powershell or vbs), which will launch the navseccli.exe with the parameters you want to check and return the status to PRTG (0 is green, 1 is Warning, 2 is Error). You have to put your code is the same folder as the NaviSecCLI program.

Some example with NaviSecCLI will be :

  • faults -list, which return the status of the hardware
  • getdisk -state, which return the status of all disks present

For my needs, to check the disks, I have done the following

  • Write a powershell script which launch the navseccli and return the status to a text file.
  • Parse the file to find if all disks are "enable". If Yes, return 0 to PRTG.

Below the code

& "C:\Program Files (x86)\PRTG Network Monitor\Custom Sensors\EXE\NaviSecCli.exe" -user Administrator -password password -h ip_address -f "C:\Program Files (x86)\PRTG Network Monitor\Custom Sensors\EXE\file.txt" -scope 0 getdisk -state

# Path and Filter
$Path = "C:\Program Files (x86)\PRTG Network Monitor\Custom Sensors\EXE\file.txt"
$regex = "enable"

#Number of disks in the SAN
$disks_to_check = 29

# Result of the filter
$string = select-string -Path $Path -pattern $regex -AllMatches | %{$_.matches} | %{$_.value}

#Number of disks OK and NOK
$disks_ok = $disks_to_check - $string.count

# PRTG Sensor condition 
if ($disks_ok -eq 0) {
  write-host "0:$disks_to_check Disks OK"
  exit 0
}  

else {
  write-host "2:$disks_ok Disks failure"
  exit 2
}

endif 
  • Add a "EXE" sensor in PRTG which will call my powershell script.

EDIT BY PAESSLER: Adjusted formatting of the code block
Fix the problem that the "NaviSecCLI" will launch only first time. You have to prefix the command with an "&", put the full path rather than ".\" and use the "-f" for the output.

If there is an MIB file available you can convert it using our MIB Importer and then use the resulting OIDLIB file with an SNMP Library sensor.

The EMC VNX devices support SNMP polling. They do have some support for SNMP traps. It appears other vendors have a virtualization and storage management products which leverage SMI-S providers to obtain data. Does PRTG have a comparable solution?

Unfortunately EMC has a very poor support of SMNP, for most systems just a few traps are implemented.

Do have a plan to implement some addition sensors to monitor EMC systems other than SNMP?

Kind regards, Christoph

We did run evaluation tests on this, however decided to put it on the wishlist, as the requests have been to few. So this is only on the wish list.

As mentioned, this can still take a while. The feature will be mentioned in our release notes. Please bear with us.

I setup my own PowerShell script which seems to work quite well. I did have issues with the NaviSECCli not closing automatically after running the query and found out I had to use quotations around the arguments to get it to close properly.

This script has a couple of improvements, namely it'll calculate the number of disks in the array without manual intervention, it'll throw a WARNING state when rebuilding and equalising the disks, and it doesn't need to write a txt file to provide results, it's all done with the $Query variable. NaviSECCli is also installed and called from it's normal directory.

Lastly, I've specified -ExecutionPolicy Bypass in the parameters field in PRTG to bypass PowerShell's script execution security. Not sure if it works properly, but worth a shot.

You can alter the script to provide different monitoring by using faults -list and other useful commands, modifying appropriately.

#Query the SAN for current disk status
$Query = & "C:\Program Files (x86)\EMC\Navisphere CLI\NaviSECCli.exe" "-User <Username> -Password <Password> -h <IPAddress> -Scope <scope> getdisk -state"

#Calculate the total number of disks
$TotalDisks = (Select-String -InputObject $Query -Pattern "disk" -AllMatches).Matches.Count

#Calculate the number of disks in notable states
$RebuildingDisks = (Select-String -InputObject $Query -Pattern "rebuilding|equalizing" -AllMatches).Matches.Count
$FailedDisks = (Select-String -InputObject $Query -Pattern "failed" -AllMatches).Matches.Count

#PRTG sensor condition
If ($FailedDisks -eq 0 -and $RebuildingDisks -eq 0) {
    Write-Host "0:Disks OK"
    Exit 0
} ElseIf ($FailedDisks -eq 0 -and $RebuildingDisks -gt 0) {
    Write-Host "1:WARNING $TotalDisks disk(s) rebuilding or equalising"
    Exit 1
} ElseIf ($FailedDisks -gt 0) {
    Write-Host "2:FAILURE $FailedDisks disk(s) failed"
    Exit 2
}

I modified the script a little. This adjustment will set Green, Yellow, Red error levels with the sensors. Count the number of hotspares and rebuilding disk

#Query the SAN for current disk status
$Query = & "C:\Program Files (x86)\EMC\Navisphere CLI\NaviSECCli.exe" ""-h host -User username -Password password -Scope 0 getdisk -state""

#Calculate the total number of disks
$TotalDisks = (Select-String -InputObject $Query -Pattern "disk" -AllMatches).Matches.Count

#Calculate the total number of Hot Spares
$HotSpares = (Select-String -InputObject $Query -Pattern "hot" -AllMatches).Matches.Count

#Calculate the number of disks in notable states
$RebuildingDisks = (Select-String -InputObject $Query -Pattern "rebuilding|equalizing" -AllMatches).Matches.Count
$FailedDisks = (Select-String -InputObject $Query -Pattern "failed|faulted|fault" -AllMatches).Matches.Count

Yeah nice script, used it as a base to create one to monitor the storage utilisation of a pool. Only does Pool with ID 0 for now but that's all I have so works for me.

#Query the SAN for storage pool free space
$Query = & "C:\Program Files (x86)\EMC\Navisphere CLI\NaviSECCli.exe" ""-h 10.18.150.90 -User <admin username> -Password <password> -Scope 0 storagepool -list -id 0 -prcntFull"" | Out-String

#remove whitespace
$Query = $Query.Trim()

#just get the last 7 digits of the result which contains the percent utilization
$percentFull = $Query.Substring($Query.Length - 7,7)

#convert result to int
$intvalue = $percentFull -as[int]

write-host "<prtg>"
write-host "<result>"
write-host "<channel>Percent Full</channel>"
write-host "<customunit>%</customunit>"
write-host "<value>$intvalue</value>"
write-host "</result>"
#PRTG message display

If ($intvalue -gt 90) {
    write-host "<text>Storage Pool Usage Critical</text>"
    write-host "<error>1</error>"
} ElseIf ($intvalue -gt 70 ) {
    write-host "<text>WARNING Storage Pool Usage High</text>"
} Else {
    write-host "<text>All OK</text>"
}

write-host "</prtg>"

Hi,

I got this result using Custom EXE sensor launching powershell script:

Response not wellformed: "(<prtg> <result> <channel>Total Disks</channel> <customunit>Disk(s)</customunit> <value></value> </result> <result> <channel>Hot Spare Disks</channel> <customunit>Disk(s)</customunit> <value></value> </result> </prtg> )" (code: PE132)
<?xml version="1.0" encoding="UTF-8" ?>
	<prtg>
		<result>
			<channel>Total Disks</channel>
			<customunit>Disk(s)</customunit>
		</result>
		<result>
			<channel>Hot Spare Disks</channel>
			<customunit>Disk(s)</customunit>
		</result>
	</prtg>

Anything to do on sensor configuration?

thanks

I'm afraid that I'm not able to test the script, but the script's author may be able to assist you. Basically it doesn't work because your result is missing the <value> tags, for both channels. Unfortunately I'm not able to tell you why this happens.

You can further troubleshoot it yourself by running the script in the Powershell ISE. Check what result you get there, you can then check what value is stored in the variables or if anything else is going wrong.

Update: As of version 18.1.37, PRTG includes 5 sensor types that enable you to monitor your Dell EMC storage systems out of the box! The sensors use the REST API of Dell EMC devices to show you health status and other important measurements of your Dell EMC storage components.
