The project has been running for several days and summarizes the reasons:

1. Autodiscover registration monitoring does not understand the principles, and many legacy scripts are not supported before.
2. I don't know the script completely yet, so I'll have to look at it when I have time
3. Or ideas, solutions to the problem tens of millions of ways, don't hang on a tree, try several methods of death I'm lazy, I planned to use jmx monitoring before, found that the company used supervisorctl management jar package to start, I also used it for the first time, do not elaborate here.

4. Use the jstat command to get the parameters, use the scheduled task here, put it in the script before, the service is dead.

Monitoring Indicators:
S0C: Capacity (in bytes) of the first survivor in the younger generation
 S1C: Capacity (in bytes) of the second survivor in the younger generation
 S0U: The first survivor of the younger generation is currently using space (bytes)
S1U: The second survivor of the younger generation is currently using space (bytes)
EC: Capacity (in bytes) of Eden in the younger generation
 EU: Eden (Garden of Eden) is using space (bytes) in the younger generation
 OC:Old generation capacity (bytes)
Space (bytes) currently in use in OU:Old generation
 Capacity (bytes) of PC:Perm (persistent generation)
PU:Perm (persistent generation) Space in use (bytes)
YGC: The number of GCs in the younger generation from application startup to sampling!
YGCT: Time taken from application startup to gc in the younger generation at sampling time (s)
FGC: Number of GC from application startup to old generation (full gc) sampling!
FGCT: Time taken from application startup to old generation (full gc)gc of sampling (s)

Here's a note about permissions: sudo Secret-Free Configuration

visudo

zabbix  ALL=(ALL)       NOPASSWD: ALL. #Secret-free
Defaults:zabbix    !requiretty        #No login required

Where the Zabbix configuration file needs to be modified:

AllowRoot=1                            #AllowRoot=1 (allow running as root)

Note: Restart the zabbix-agent after modifying the configuration and use the zabbix_get to get the data to see if it is available properly
