Status

Various cluster statuses are available in Weaviate.

Liveness

The live endpoint checks if the application is alive. You can use it for a Kubernetes liveness probe.

Usage

The endpoint accepts a GET request:

GET /v1/.well-known/live

The endpoint returns HTTP status code 200 if the application is able to respond to HTTP requests.

import weaviate

client = weaviate.connect_to_local()

    print(client.is_live())

finally:
    client.close()

import weaviate from 'weaviate-client';

const client = await weaviate.connectToLocal()
const response = await client.isLive()

console.log(response)

package main

import (
  "context"
  "fmt"

  "github.com/weaviate/weaviate-go-client/v5/weaviate"
)

func main() {
  cfg := weaviate.Config{
    Host:   "localhost:8080",
    Scheme: "http",
  }
  client, err := weaviate.NewClient(cfg)
  if err != nil {
    panic(err)
  }

  isLive, err := client.Misc().LiveChecker().Do(context.Background())
  if err != nil {
    panic(err)
  }
  fmt.Printf("%v", isLive)
}

package io.weaviate;

import io.weaviate.client.Config;
import io.weaviate.client.WeaviateClient;
import io.weaviate.client.base.Result;

public class App {
  public static void main(String[] args) {
    Config config = new Config("http", "localhost:8080");
    WeaviateClient client = new WeaviateClient(config);

    Result<Boolean> result = client.misc().liveChecker().run();

    if (result.hasErrors()) {
      System.out.println(result.getError());
      return;
    }
    System.out.println(result.getResult());
  }
}

curl http://localhost:8080/v1/.well-known/live

The endpoint returns HTTP status code 200 if the application is able to respond to HTTP requests.

Readiness

The ready endpoint checks if the application is ready to receive traffic. You can use it for Kubernetes readiness probe.

Usage

The discovery endpoint accepts a GET request:

GET /v1/.well-known/ready

The endpoint returns HTTP status code 200 if the application is able to respond to HTTP requests. If the application is currently unable to serve traffic, the endpoint returns HTTP status code 503.

If the application is unavailable and you have horizontal replicas of Weaviate that can receive traffic, redirect traffic to one of the replicas.

    }
    System.out.println(result.getResult());
  }
}

curl http://localhost:8080/v1/.well-known/ready

Schema synchronization

The v1//schema/cluster-status endpoint displays the status of the schema synchronization. The endpoint returns the following fields:

• healthy: The status of the schema synchronization.
• hostname: The hostname of the Weaviate instance.
• ignoreSchemaSync: Whether to ignore the cluster check at startup (for recovery from an out-of-sync situation).
• nodeCount: The number of nodes in the cluster.

Example response:

{
    "healthy": true,
    "hostname": "node1",
    "ignoreSchemaSync": false,
    "nodeCount": 3
}
