This is Cacti's Services monitoring plugin. Based on Webseer plugin. This plugin allows you to add service monitoring to Cacti. You simply add service check, allow service specific test (like certificate test) and you can add the expected response. Servcheck periodically run test and notify if a service check fails. The plugin records statistics about the connection, it's response, and can alert when the status changes.
This plugin, like many others, integrates with Cacti's Maintenance or 'maint' plugin so you can setup maintenance schedules so that known times when a service is going to be down can be configured so that escallation does not needlessly take place during maintenance periods.
To install the servcheck plugin, simply copy the plugin_servcheck directory to Cacti's plugins directory and rename it to simply 'servcheck'. Once you have done this, goto Cacti's Plugin Management page, Install and Enable the servcheck. Once this is complete, you can grant users permission to create service checks for various services.
Go to Management -> Service Checker
You need install libcurl library. For more information about Curl/libcurl visit https://www.php.net/manual/en/book.curl.php
Test can return more results. First result is from curl. There is a lot of information about curl connection. Second result is returned data on which you can perform searches.
Each test has icon for display last result. You can use it for creation of search string.
Each tests return specific data: HTTP and HTTPS - returns webpage SMTP, SMTPS - only connect to SMTP server and displays EHLO/HELO POP3, POP3S - try to login and display first unread message IMAP, IMAPS - try to login and display unread messages in inbox DNS - try to resolve A record and return answer LDAP and LDAPS - do searching in LDAP FTP, FTPS - try to login and return directory listing TFTP - try to download specific file SCP - try to login and download specific file SMB, SMBS - try to login and download specific file.
Recomendation for tests with download - please download only small not binary files.
Default Libcurl build doesn't compile all services. You have to compile again for SMB, LDAP, ...
For POP3 and IMAP tests is better insert correct username and password. Without credentials, curl will return incorrect result.
SCP is in insecure mode - doesn't check SSH server key!
Do not test other servers without permission!
Servcheck uses a file of certificates from common root CAs to check certificates. This will work for certificates issued by common CAs. If you are using a custom CA (for example, in a Microsoft AD environment), the test for that certificate will fail because servcheck does not know your CA. You must upload the entire chain (CA certificate and intermediate certificates). You then associate these with the test where the certificate issued by your CA
