get correct status of PM2 application after deploy/redeploy - jenkins

Question

I'm trying to use PM2 for deployment purposes, and so at the end of my deployment process I do
pm2 startOrReload staging.json --env preprod
and I get this :
16:26:12 ‘staging/current’ -> ‘/srv/pb/dev/v0.0.6-85-g755a611’
16:26:12 [PM2] Applying action reloadProcessId on app [pb1](ids: 0)
16:26:13 [PM2] [pb1](0) ✓
16:26:13 ┌──────────┬────┬──────┬───────┬────────┬─────────┬────────┬─────────────┬──────────┐
16:26:13 │ App name │ id │ mode │ pid │ status │ restart │ uptime │ memory │ watching │
16:26:13 ├──────────┼────┼──────┼───────┼────────┼─────────┼────────┼─────────────┼──────────┤
16:26:13 │ pb1 │ 0 │ fork │ 30180 │ online │ 111 │ 0s │ 19.805 MB │ enabled │
16:26:13 └──────────┴────┴──────┴───────┴────────┴─────────┴────────┴─────────────┴──────────┘
as you can notice the status is online regardless of the deploy being sucessfull or not;
And is marking the Jenkins build as success when is not. immediately afterward if you do a
pm2 list
you get the correct status offline
So is there a way to get the correct status via API or something so that I can mark the build as failure

Answer 1

1) You can get the current status in the JSON format from CLI:
pm2 jlist
pm2 prettylist
2) Or you can connect to pm2 instance programmatically:
var pm2 = require('pm2');
pm2.connect( function(err) {
if (err) process.exit();
pm2.list( function(err,list) {
list.forEach( function(e) {
console.log( e.name, e.pm2_env.status );
});
pm2.disconnect();
});
});
3) Or you can use keymetrics monitoring.
