BUG: Provide valid Sync Status for Nethermind EC

[daverolo]

Describe the bug Sync Status for Nethermind EC is invalid.

To Reproduce Steps to reproduce the behavior:

1. Setup a fresh node with Nethermind EC
2. Select the "Control" Tab
3. See invalid values for Nethermind in "Sync Status" Widget

Expected behavior A valid representation of current Nethermind EC Sync Status

Screenshots

Desktop (please complete the following information):

• OS: macOS
• Launcher version: 2.0.0-RC.6

Node (please complete the following information):

• OS: Ubuntu 22.04
• Affected service: Nethermind EC v1.14.3

Additional context Nethermind EC does not provide data for Prometheus at all to retrieve a valid Sync Status. The currently tested labels ['nethermind_blocks','nethermind_blocks_sealed'] are wrong. An option for the future could be to request the Sycn Status via RPC-API (untested) .

Dear @daverolo: Currently syncing with snap sync NM+Prysm. Metric you have referenced works.

@daverolo Could you please compare the arguments you have used to run it?

Here are mine:

.\Nethermind.Runner.exe -c mainnet -dd C:/work/ethdata --Metrics.Enabled true --Metrics.ExposePort=9091 --JsonRpc.Enabled true --JsonRpc.Port 8547 --Sync.SnapSync true --JsonRpc.JwtSecretFile C:/ethereum/consensus/jwt.hex

.\beacon-chain-v3.1.2-windows-amd64.exe --mainnet --execution-endpoint=http://localhost:8551/ --jwt-secret=C:/ethereum/consensus/jwt.hex --checkpoint-sync-url=https://beaconstate.info/ --genesis-beacon-api-url=https://beaconstate.info/ --datadir=C:/work/ethdata

with

.\prometheus.exe --config.file=./prometheus.yml --storage.tsdb.path=./prometheus --storage.tsdb.retention=200h --web.enable-lifecycle

and /prometheus.yml:

global:
  scrape_interval:     5s
  evaluation_interval: 5s

scrape_configs:
  - job_name: 'nm'
    honor_labels: true
    static_configs:
    - targets: ['localhost:9091']

fixed with #1018, thanks for your input @OlegJakushkin
