Support for application metrics #1320

acuarica · 2024-04-02T22:24:01Z

Does Sourcify support exporting application metrics to be ingested by Prometheus/Grafana? For example, something like hashgraph/hedera-sourcify#131

Is this something that you would consider including?

I think this is something we can include. I consider making this optional in the config (e.g. metrics: {enabled: true}) as this is not something essential to run Sourcify. WDYT?

Are you using the standard dashboard from the Grafana dashboard shared there or have you added more information? If you could share a full screenshot of the current dashboard if would be helpful.

Another thing to consider is, we moved away from the events SourcifyEventManager. To track verifications etc. we simply print logs of important occurrences e.g.

sourcify/packages/lib-sourcify/src/lib/verification.ts

Lines 247 to 253 in d8dc64d

    
           logInfo('Verified contract', { 
        
             name: checkedContract.name, 
        
             address, 
        
             chainId: sourcifyChain.chainId, 
        
             runtimeMatch: match.runtimeMatch, 
        
             creationMatch: match.creationMatch, 
        
           });

These are printed in machine readable JSON in production (i.e. NODE_ENV=production) and a nice line-log format otherwise. On production, these logs are then parsed by Loki to process and view them on Grafana

We can then derive miscellaneous metrics from these logs:

This is how it looks locally:

For requests etc. we mostly use the nginx logs.

That would be great.

Indeed, we have something like

Sounds great, we can use the same logs strategy in our infra to get metrics. No need to include additional metrics.

I'll send a PR soon to get this implemented, feel free to assign this to me.

kuzdogan · 2024-04-18T08:29:33Z

Assigned :) lmk if you need anything

Roughly, you can put this route under routes.ts to be enabled optionally by looking at the config if(config.get("metrics.enabled")

Sounds good, thanks for the heads up.

acuarica · 2024-06-14T14:45:25Z

Hi Kaan and team,

We are continuing with the metrics and analytics on our side. For the moment, we decided to get metrics from Loki as you suggested. Here's some panel example similar to what you showed

Given we share the same log format (after we updated our Sourcify instance to match yours), do you think you can share the Grafana dashboards to visualize these logs? (of course I understand if this is too much to ask)

kuzdogan · 2024-06-19T08:03:15Z

@acuarica Hey nice, sure I can share but our dashboards are quite rudimentary so don't expect much :) Also not sure if we have the exact setups.

We have ingress_user and namespace under which the sourcify project is listed. Then there are k8s pods and containers.
