To verify the status of the capability of XpoLog to measure CPU/Memory/Disk Space (Metrics) of a remote server in XpoLog's Analytics go to ' Analytics -> Administration -> Logs' and select 'View by Servers', click a server/right click a server and click "Verify Connection" to check the connectivity and get a metrics measurements validation.
 

 

Windows machines:

1) RPC server is unavailable / Access is denied
- Problem description: Cannot access the RPC server on a remote computer. 
- Probable cause: This can be caused by the Windows Firewall service and Distributed Component Object Model (DCOM).
- Solution: To allow connection to the remote computer:
a. Make sure that the used host name is valid and that the server is running.
b. Ensure that the user account that XpoLog uses is an administrator on the remote computer.
If the XpoLog user account is not an administrator on the remote computer, but the user account has Remote Enable permission on the remote computer, then the user must also be given DCOM Remote Launch and Remote Activation privileges on the remote computer by running Dcomcnfg.exe at the command prompt.
c. Allow for remote administration on the remote computer. 
You can use either the Group Policy editor (Gpedit.msc) or a script to enable the Windows Firewall: Allow remote administration exception, or use a NETSH firewall command at the command prompt to allow for remote administration on the remote computer. 
The following command enables this feature:
netsh firewall set service RemoteAdmin enable

If you would rather use the Group Policy editor than the NETSH commands above, use the following steps in the Group Policy editor (Gpedit.msc) to enable "Allow Remote Administration" on the remote computer. 
- Under the Local Computer Policy heading, double-click Computer Configuration. 
- Double-click Administrative Templates, Network, Network Connections, and then Windows Firewall. 
- If the computer is in the domain, then double-click Domain Profile; otherwise, double-click Standard Profile. 
- Click Windows Firewall: Allow remote administration exception. 
- On the Action menu, select Properties. 
- Click Enable, and then click OK.

2)CScript is not recognized
- Problem description: The dynamic link library (DLL) VBScript.DLL is not properly installed on your computer. 
- Probable cause: It is likely this file (VBScript.DLL) is missing
- Solution: run "regsvr32 VBScript" in a Command Prompt.

 

UNIX machines:

1) Command not found
- Problem description: One or more of the following commands executed on the machine could not be found - 
"date", "top", "df", "free"
- Solution: Ensure permissions are given to the user XpoLog is using for these commands. If required, install the command/s or the missing package or consult with your system administrator.
2) Account is missing
- Problem description: Failed to find the account associated with a host.
- Solution: Make sure that the account associated with this the host is defined properly:
Go to 'Analytics -> Administration -> Logs' and select 'View by Servers'
Select the server and click 'Verify Connection'. If the verification fails, click 'Edit Server' and select the 'Metrics' tab.
Make sure the 'Connection Details' is set. If not, click 'new' and enter new connection details. 
Click 'Save' in the account page to save the newly defined account and then 'Save' in the server's edit window to save the server definitions.
3) Date command / format is missing
- Problem description: Failed to get date from the host. 
- Solution: Contact your XpoLog administrator or XpoLog Support to verify XpoLog's configuration.
4) Failed to fetch
- Problem description: The metrics data (cpu, memory or disk space) could not be fetched
- Solution: Contact your XpoLog administrator or XpoLog Support to verify XpoLog's configuration.
5) Server type is unknown
- Problem description: May be caused when a server has a "NA" as the server type (like a server that has been created through a database account)
- Solution: Edit the server and set a proper connectivity account so that XpoLog can use to measure metrics, save it and verify that the connection is valid.
