3.启动redis-shake后
可部署多个 redis-shake 10.111.11.12:8888 10.111.11.12:8889 10.111.11.12:8890

二.json-exporter配置
1.Dockerfile
FROM prometheuscommunity/json-exporter:latest USER root RUN mkdir -p /opt WORKDIR /opt COPY config.yml /opt/
2.config.yml
根据上边返回的json数据，制定自己需要的监控模版，部署json-exporter 10.111.11.11:7979
modules:
default:
headers:
X-Dummy: my-test-header
metrics:
- name: shake_consistent
help: Example of sub-level value scrapes from a json
path: '{.consistent}'
labels:
start_time: '{.start_time}'
- name: shake_total_entries_count
type: object
help: Example of sub-level value scrapes from a json
path: '{.total_entries_count}'
values:
read_count: '{.read_count}' # static value
read_ops: '{.read_ops}' # dynamic value
write_count: '{.write_count}'
write_ops: '{.write_ops}'
- name: shake_per_cmd_entries_count_restore
type: object
help: Example of sub-level value scrapes from a json
path: "{.per_cmd_entries_count.RESTORE}"
values:
read_count: '{.read_count}'

read_ops: '{.read_ops}'
write_count: '{.write_count}'

values:
rdb_file_size_bytes: '{.rdb_file_size_bytes}'
rdb_received_bytes: '{.rdb_received_bytes}'
rdb_sent_bytes: '{.rdb_sent_bytes}'
aof_received_offset: '{.aof_received_offset}'
aof_sent_offset: '{.aof_sent_offset}'
aof_received_bytes: '{.aof_received_bytes}'
- name: shake_writer
type: object

path: "{.writer}"
labels:
name: '{.name}' # dynamic label
values:
unanswered_bytes: '{.unanswered_bytes}'
unanswered_entries: '{.unanswered_entries}'
三.prometheus配置
1.prometheus.yml
global:
scrape_interval: 15s
evaluation_interval: 15s
scrape_configs:
- job_name: json_exporter
metrics_path: /probe
file_sd_configs:
- files:
- 'redis-shake.json'
relabel_configs:
- source_labels: [__address__]
target_label: __param_target
- source_labels: [__param_target]
target_label: instance
- target_label: __address__
replacement: 10.111.11.11:7979 # json-exporter地址
2.redis-shake.json
单独的文件配置可实现动态加载，同时可添加自定义的标签在文件中
[
# labels为自定义的标签，targets为部署各个redis-shake地址
{"labels": {"env-1":"团队1"},"targets": ["http://10.111.11.12:8888"]},
{"labels": {"env-1":"团队2"},"targets": ["http://10.111.11.12:8889"]},
{"labels": {"env-1":"团队3"},"targets": ["http://10.111.11.12:8890"]}
]
四.grafana
上边的都配置好，把自己的peometheus数据源添加到grafana中，就可以设置自己想要的监控界面了
