Kafka management utils
Project description
[](https://travis-ci.org/Yelp/kafka-utils)
# Kafka-Utils
A suite of python tools to interact and manage Apache Kafka clusters.
Kafka-Utils runs on python2.7 and python3.
## Configuration
Kafka-Utils reads cluster configuration needed to access Kafka clusters from yaml files. Each cluster is identified by *type* and *name*.
Multiple clusters of the same type should be listed in the same `type.yaml` file.
The yaml files are read from `$KAFKA_DISCOVERY_DIR`, `$HOME/.kafka_discovery` and `/etc/kafka_discovery`, the former overrides the latter.
Sample configuration for `sample_type` cluster at `/etc/kafka_discovery/sample_type.yaml`
```yaml
---
clusters:
cluster-1:
broker_list:
- "cluster-elb-1:9092"
zookeeper: "11.11.11.111:2181,11.11.11.112:2181,11.11.11.113:2181/kafka-1"
cluster-2:
broker_list:
- "cluster-elb-2:9092"
zookeeper: "11.11.11.211:2181,11.11.11.212:2181,11.11.11.213:2181/kafka-2"
local_config:
cluster: cluster-1
```
## Install
From PyPI:
```shell
$ pip install kafka-utils
```
## Kafka-Utils command-line interface
### List all clusters
```shell
$ kafka-utils
cluster-type sample_type:
cluster-name: cluster-1
broker-list: cluster-elb-1:9092
zookeeper: 11.11.11.111:2181,11.11.11.112:2181,11.11.11.113:2181/kafka-1
cluster-name: cluster-2
broker-list: cluster-elb-2:9092
zookeeper: 11.11.11.211:2181,11.11.11.212:2181,11.11.11.213:2181/kafka-2
```
### Get consumer offsets
```shell
$ kafka-consumer-manager --cluster-type sample_type offset_get sample_consumer
```
### Get consumer watermarks
```shell
$ kafka-consumer-manager --cluster-type sample_type get_topic_watermark sample.topic
```
### Rebalance cluster cluster1 of type sample_cluster
```shell
$ kafka-cluster-manager --cluster-type sample_type --cluster-name cluster1
--apply rebalance --brokers --leaders --max-partition-movements 10
--max-leader-changes 15
```
### Rolling-restart a cluster
```shell
$ kafka-rolling-restart --cluster-type sample_type
```
### Check in-sync replicas
```shell
$ kafka-check --cluster-type sample_type min_isr
```
### Check number of unavailable replicas
```shell
$ kafka-check --cluster-type sample_type replica_unavailability
```
