Prometheus exporter for Chia node metrics

Overview

chia_exporter

Prometheus metric collector for Chia nodes, using the local RPC API

Building and Running

With the Go compiler tools installed:

go build

Run ./chia_exporter -h to see the command configuration options:

-cert string
      The full node SSL certificate. (default "$HOME/.chia/mainnet/config/ssl/full_node/private_full_node.crt")
-key string
      The full node SSL key. (default "$HOME/.chia/mainnet/config/ssl/full_node/private_full_node.key")
-listen string
      The address to listen on for HTTP requests. (default ":9133")
-url string
      The base URL for the full node RPC endpoint. (default "https://localhost:8555")
-wallet string
      The base URL for the wallet RPC endpoint. (default "https://localhost:9256")

Blockchain

Various node and blockchain metrics are collected from the get_blockchain_state endpoint.

Connections

The number of connections are collected for each node type from the get_connections endpoint.

Node types (from chia/server/outbound_message.py):

FULL_NODE = 1
HARVESTER = 2
FARMER = 3
TIMELORD = 4
INTRODUCER = 5
WALLET = 6

Wallet

The wallet balances are collected from the get_wallet_balance endpoint.

  • Rebuild Dockerfile to run chia_exporter as a shim on Chia

    Rebuild Dockerfile to run chia_exporter as a shim on Chia

    The latest official Chia image is used as a base and the exporter defaults export it's metrics. Further env configuration is needed to make the underlying Chia setup do what you want, for example be a full_node or harvester.

    This is far from ideal as a solution since it violates the separation of concerns running the exporter in the same container instead of as a sidecar. Right now though it's sort of necessary since Chia defaults to only listening on 127.0.0.1, doesn't have any config hooks to override that per RPC service and doesn't even have a configure switch for changing the local_hostname which is used for RPC service binding. Thus the next best thing is to bring the exporter into the same container so it can access the default localhost-only RPC endpoints .

  • netspace overflow and sync status gone

    netspace overflow and sync status gone

    (Sadly) the chia netspace has gone up a lot the last 12 hours and now doesn't fit into int64 anymore:

    2021/05/22 04:51:25 error decoding get_blockchain_state response: json: cannot unmarshal number 9566905519282954240 into Go struct field .blockchain_state.Space of type int64
    

    Also the blockchain_sync_status doesn't get populated but I don't see any error in the exporter log lines..

  • Wallet fingerprint not added to metric

    Wallet fingerprint not added to metric

    When I query the /metrics endpoint I see all my wallet and balances, but the fingerprint values are missing. I had the issue with chia 1.2.3 and 1.2.5.

    It also seems to miss all other wallets (only finding wallet_id=1 and I have many wallets)

    # TYPE chia_wallet_sync_status gauge
    chia_wallet_sync_status{wallet_fingerprint="",wallet_id="1"} 2
    # HELP go_gc_duration_seconds A summary of the pause duration of garbage collection cycles.
    
    

    Also it is timing out on:

    2021/09/07 12:09:42 error calling get_wallet_balance: Post "https://localhost:9256/get_wallet_balance": context deadline exceeded (Client.Timeout exceeded while awaiting headers)

    In chia my wallets take some time to answer, I think that timeout is causing me problems. Can I increase it somewhere?

    Added details of the plot files, so we can distinguish OG and portables ones.

    I've created a Dockerfile for this project for my own use, and thought it best to submit a PR in case it would be wanted as part of the project.

    If accepted, let me know if you would want any documentation on how to build/deploy using this and I can add a separate PR to add a section to the README :smiley:

    Feature request - monitor multiple harvesters

    Dear @retzkek , thanks for putting together your docker-compose stack chiamon which includes this chia_exporter.

    I am currently evaluating this setup which looks promising, but if I am not mistaken, there is no option yet to monitor multiple (n) harvesters.

    Any plans to do so in the near future?

  • Validate endpoint URLs, rename flag url to full_node

    Validate endpoint URLs, rename flag url to full_node

    • Validation checks endpoints are valid URLs and start with 'https://' since not enabling SSL will cause weird EOF errors due to the protocol mismatch
    • Protocol mismatch is a fatal error but other validation failures result in that endpoint being disabled. This allows for selectively disabling unwanted endpoints: -farmer=disabled and Fixes #15
    • The old '-url' flag becomes '-full_node' for consistency but the old flag will continue to work as well.

  • All RPC endpoints are queried regardless of flags

    All RPC endpoints are queried regardless of flags

    During testing for #14 I noticed that even if I don't provide a -wallet flag and so on, the endpoint is still queried since it has a default localhost value. Even if I set the param to an empty value, i.e.: chia_exporter -wallet='' the query is still attempted:

    2021/11/11 14:10:26 error calling get_wallets: Post "/get_wallets": unsupported protocol scheme ""
    

    This means that every endpoint that the user doesn't actually care about for that exporter, is producing an error on every run, which fills up logs quick and makes it harder to debug any real issues.

    Ergo, there is no way to enable or disable which endpoints are queried. While on a monolithic setup where all pieces live on the same host this is not a problem, the moment you separate services you'll want to run multiple instances of the exporter with different scopes. For example, my setup right now is one full_node and two harvesters. For the full_node exporter I would want to disable the harvester requests and on the harvester exporters only request the local harvester.

    Since it's more user-friendly to default to pulling everything from the localhost I understand wanting to set the default value to match that. What I'd recommend is that setting the string to 'false' or empty would be interpreted as disabling that portion.

    TL;DR; for any setup that's more complex than a naive monolithic one, the ability to selectively enable endpoints would be grand.

  • Automate building of Docker images into the GitHub registry.

    Automate building of Docker images into the GitHub registry.

    There are already 3rd party images published on Dockerhub that are wildly out of date. So one automatically up to date official image is probably better than having people rely on unofficial images.

    • Any push to the master branch updates the :latest label
    • Any tag push to master will also be labeled with the tag name, so your releases will get stable labels.
    • Any push to any other branch is labeled with the branch name and the short hash id of the commit.

  • Add collect for get_harvesters

    Add collect for get_harvesters

    This collects metrics from the farmer get_harvesters endpoint (mentioned in the chia-blockhain v1.2.0 release notes but not documented in the wiki). Most of the same data as get_plots from the harvester is collected but this collects once for all remote/connected harvesters. Metrics for plot count have labels for pool_public_key, pool_contract_puzzle_hash and size. These labels can be used to tell if a plot is portable or solo or if you plot different size plots etc.

    • sum(chia_farmer_plots{pool_contract_puzzle_hash!=""}) - total portable plots across all harvesters
    • sum(chia_farmer_plots{pool_public_key!=""}) - total solo plots across all harvesters

    This may obsolete func collectPlots.
