simulator_snapshot.json: Process Lists

STiAT
Helper

Hi there,


I'm trying to build a simulator_snapshot.json out of the process list of a host:

Given by the plugin:

ProcessSnapshotEntry(
group_id=5845565441870040532,
 node_id=0,
 group_instance_id=14866227715756740309,
 process_type=2,
 group_name='Oracle Database',
 processes=[ProcessInfo(
pid=61354,
 process_name='ora_s000_gccon',
 properties={'ExePath': '/oracle/product/19/gccon/bin/oracle',
 'ParentPid': '1',
 'WorkDir': '/oracle/product/19/gccon/dbs'}),
 ProcessInfo(
pid=115577,
 process_name='oracle_115577_g',
 properties={'CmdLine': '(LOCAL=NO)',
 'ExePath': '/oracle/product/19/gccon/bin/oracle',
 'ParentPid': '1',
 'WorkDir': '/oracle/product/19/gccon/dbs'}),
 ProcessInfo(
pid=75379,
 process_name='ora_w00a_gccon',
 properties={'ExePath': '/oracle/product/19/gccon/bin/oracle',
 'ParentPid': '1',
 'WorkDir': '/oracle/product/19/gccon/dbs'}),

The created simulator_snapshot.json

{
    "entries": [
        {
            "group_name": "Oracle Listeners",
            "processes":[
                {
                    "process_name":"tnslsnr",
                    "properties": {
                        "CmdLine": "listener -inherit",
                        "ExePath": "/oracle/product/19/gccon/bin/tnslsnr",
                        "ListeningPorts": "1522",
                        "ParentPid": "1",
                        "PortBindings": "127.0.0.1_1522",
                        "WorkDir": "/"
                    }
                }
            ],
            "properties": {"Technologies": "ORACLE_DB"}
        },
        {
            "group_name": "Oracle Database",
            "processes":[
                {
                    "process_name":"ora_s000_gccon",
                    "properties": {
                        "ExePath": "/oracle/product/19/gccon/bin/oracle",
                        "ParentPid": "1",
                        "WorkDir": "/oracle/product/19/gccon/dbs"}
                },
                {
                    "process_name":"oracle_115577_g",
                    "properties:": {
                        "CmdLine": "(LOCAL=NO)",
                        "ExePath": "/oracle/product/19/gccon/bin/oracle",
                        "ParentPid": "1",
                        "WorkDir": "/oracle/product/19/gccon/dbs"
                    }
                },
                {
                    "process_name":"ora_w00a_gccon",
                    "properties": {
                        "ExePath": "/oracle/product/19/gccon/bin/oracle",
                        "ParentPid": "1",
                        "WorkDir": "/oracle/product/19/gccon/dbs"
                    }
                }
            ],
            "properties": {"Technologies": "ORACLE_DB"}
        }
    ]
}

The issue I have here is that I get an exception due to the "properties"

Validating plugin.json against schema, it seems it has an issue with the multiple-processes in the same group ... but that's what I get out of the plugin snapshot.

How to create a simulator_snapshot.json properly if a group has more process instances?

Hi, you were so close! Instead of:

"properties:"

make it:

"properties"

and it'll work (I've tested it locally).

Oh damn, blind to the own stuff ... thanks for looking at this, sometimes it needs fresh eyes to see the obvious!

No worries, I spotted it thanks to the json highlighting of notepad++.
