serve-prometheus

Publish this hotkey's prometheus metrics endpoint (ip:port) for a subnet.

Advertises where this neuron's prometheus metrics can be scraped, separate from the axon endpoint used for inter-neuron traffic. Signed by the hotkey, which must be registered on the subnet, and subject to the same serving rate limit as serve_axon. Like the axon calls, this only writes chain data — running the metrics server is up to the caller.

Signer	Pallet	Wraps
`hotkey`	SubtensorModule	`SubtensorModule.serve_prometheus`

Parameters

Parameter	Type	Required	Description
`netuid`	integer	yes	Subnet on which to publish the endpoint.
`ip`	string	yes	Public IPv4 or IPv6 address of the endpoint, in standard dotted or colon notation.
`port`	integer	yes	TCP port the endpoint listens on.
`version`	integer	no	Version number of the serving neuron's software, stored with the endpoint.

Address parameters (--hotkey, --coldkey, --dest, ...) accept a raw ss58 address, an address-book or proxy-book name, or a local wallet/hotkey name.

CLI

Preview with --dry-run (shows fee, effects, and policy result without submitting), then submit:

btcli tx serve-prometheus \
  --netuid <int> \
  --ip <value> \
  --port <int> --dry-run
btcli tx serve-prometheus \
  --netuid <int> \
  --ip <value> \
  --port <int> -w my_coldkey

Python

import bittensor as sub
from bittensor.wallet import Wallet

wallet = Wallet(name="my_coldkey", hotkey="my_hotkey")
intent = sub.ServePrometheus(netuid=1, ip="...", port=0)

async with sub.Client("finney") as client:
    plan = await client.plan(intent, wallet)   # fee, effects, policy — no submission
    result = await client.execute(intent, wallet)
    if not result.success:
        print(result.error.code, result.error.remediation)

Or build it by op name, as an agent would:

await client.execute_tool("serve_prometheus", {...}, wallet)
