This section aims to reproduce some of the real life / production environment challenges which IT360 support team encountered in the past with its customers and the resolution offered.
Probe Status Differentiation (For Enterprise and MSP Editions)
Unable to see the discovered devices under CMDB tab of Service Desk
CPU Usage Data collection is not happening for Servers in WMI mode
Possible Cause: If the message 'Server is Initializing...' is displayed for a longer duration, the IT360 Server is experiencing some problem.
Recommended Action:
Ensure if your machine, in which ManageEngine IT360 is installed meets the Recommended / Minimum System requirements.
Ensure that all the ManageEngine IT360 Services are running. Navigate to 'Administrative Tools -> Services' in Windows Control Panel to perform the check. If not, then try restarting the service(s) once again.
If you were still unable to successfully restart the ManageEngine IT360, follow the steps below to create 'Support Information File';
Open '[IT360 Home]\bin directory' in either command prompt or through Windows explorer.
Execute the file named 'CreateSupportFile.bat'.
Change the directory to '[IT360 Home]'. You will find a folder named '[IT360 Home]\support'.

Related Queries & Explanations:
i. In Central`s 'Admin --> Probe', I could see that the Probe status and the status of all modules are indicated by Green color. What does this mean?
If the Probe status and the status of all modules are indicated by Green color, i.e. in up state (as shown in the screenshot below), then it means that the Probe registration with the Central server is complete, and there exists a proper communication and sync up between the Central and the Probe.

ii. In Central`s 'Admin --> Probe', I could see that only the 'Probe Name' is displayed, the status of the probe is indicated by Red color, and the 'Synching' status is shown as 'In progress'. What does this mean?
If the above said indications are seen (as shown in the screenshot below), then it means that the Probe registration with the Central server is complete, but there exists some issue, such as the Probe Start-up issue or Sync up issue.
[TOP]
iii. In Central`s 'Admin --> Probe', I could see that the screen is empty and no Probe details are displayed. What does this mean?
If no Probe details are displayed, when you go to Central`s 'Admin --> Probe' (as shown in the screenshot below), then it means that the probe registration with the Central server itself has failed.

Possible Cause(s):
The Software/Hardware Firewall blocks the POP/IMAP port.
The IP Address of the server, on which the ServiceDesk Plus is hosted, is blocked by either the Anti-virus program, or firewall, or both.
Both of the above points: a & b can be the causes for the firewall blocking the ports.
Error trace in logs:
avax.mail.MessagingException: Connect failed;
nested exception is:
java.net.ConnectException: Connection timed out: connect
Recommended Action:
Follow the below steps to check, if firewall is blocking the port;
Open Command Prompt.
Type 'cmd> telnet [mailservername] 110', e.g. 'cmd> telnet mail.google.com 110'
If you receive an error as shown below, then port 110 is being blocked by either the anti-virus program, or the Windows firewall, or both. There is also chances for either the mail server, or port number, or both the mail server and port number to be incorrect.

Possible Cause: If the SSL Certificate in mail server is a self-signed certificate, then it is not imported in the ServiceDesk Plus java environment, while using the POPS/IMAPS protocol.
Error trace in logs:
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
Recommended Action:
Download the file from the link given below, and extract it to the ServiceDesk Plus Home directory;
'http://bonitas.zohocorp.com/servicedesk/11Mar2010/certgeneration.zip'Run the Extracted batch file from the command prompt, using the syntax given below;
Syntax: 'gencert.bat (hostname):(port)', e.g. 'cmd> gencert.bat sdpexchnage.com:995'You will receive an exception PKIX. On supplying the value 1, a file called 'jssecacerts' is generated in the ServiceDesk Plus Home Directory.
Copy the 'jssecacerts' file under the 'jre\lib\security' folder, and restart the ServiceDesk Plus application.
Fill in values under the Mail Server Settings. Start fetching mails to check the functionality.

Error trace in logs:
'Error when processing. SO RETURNING...|com.adventnet.authentication.PasswordException: Length of the new password is greater than expected value of : 100
For any Mail fetching issue, check for the string "SO RETURNING"'.. Few lines above or below the line, which contains this string, should give more information on the error trace.Possible Cause::
When a mail comes in, ServiceDesk Plus will try to create a new user with the user name and password, same as the email address. In this case, since the email address is very long, it cannot be added to the database and throws the error message; 'Length of the new password is greater than expected value of :100'
- Error/Symptom: 2 "Unable to fetch mail, as Plain text Authentication is disabled in the mail server"
Error trace in logs:
javax.mail.MessagingException: No login methods supported!;

8. Unable to access the IT360 web client
Possibility 1:
Symptom: When I reboot IT360 [server], I can see that the IT360 related services are running in the services window. However, I am unable to access the IT360 web client.
Analysis: On analysing the wrapper.log file, a server shutdown was noticed. Subsequently, when IT360 services were started, the Applications Service module did not start. Also, on analysing the StartUpLogs_err*.txt file, a MS SQL DB Connection was refused to the Applications Service module.
Also, MS SQL is installed in the same machine where IT360 [Central Server or Probe, as applicable] is installed.
Possible Cause: Application Service may have started much earlier than the MS SQL DB and hence did not find a DB Connection.
Recommended Solution: A delayed start of IT360 solves the problem. This is achieved as follows:
Go to services.msc, select 'ManageEngine IT360 Central' service [or, 'ManageEngine IT360 Probe' service, as applicable], right click and select Properties. Change the 'Startup type' to 'Automatic (delayed start)'. Click OK.
This ensures that the IT360 services are started later than the MS SQL service. You may restart IT360 now. You should be able to access the IT360 web client.
Possible Cause: If the message 'Unable to fetch Managed Object for......' is displayed while clicking a device under the Networks tab, it means that the database has crashed.
Recommended Action:
When this error occurs, follow the below steps to resolve the problem:
Login to IT360 console as an Administrator.
Navigate to "Admin -> General -> User Management".
Edit any detail of the concerned user (who encountered the problem).
Click Update.
Log out and re-login using the same credentials.
Now, navigate to the snapshot page and check the device details.
