以下是将Grafana监控 指标、日志 与链路追踪数据收罗到GreptimeDB的完整实践指南,涵盖部署、运维、安全及扩展的全流程:
一、整体架构
图表
二、数据收罗配置
1. 指标收罗(Prometheus → GreptimeDB)
步调:
yaml
remote_write:
- url: "http://:4000/v1/prometheus/write?db=public"
sql
SELECT * FROM prometheus_metrics LIMIT 10;
2. 日志 收罗(Loki → GreptimeDB)
方案:
- 通过OpenTelemetry Collector中转
yaml
# otel-collector-config.yaml
exporters:
greptimedb:
endpoint: "greptimedb:4000"
database: "logs"
service:
pipelines:
logs:
receivers: [otlp]
exporters: [greptimedb]
ruby
@type greptimedb
host greptimedb
port 4000
database logs
3. 链路追踪(Jaeger/Tempo → GreptimeDB)
步调:
yaml
remote:
storage:
type: grpc-plugin
grpc-storage:
server: "greptimedb:4001"
yaml
exporters:
greptimedb:
traces_endpoint: "http://greptimedb:4000/v1/otlp/traces"
三、Grafana数据源配置
yaml
datasources:
- name: GreptimeDB
type: greptimedb-datasource
url: http://greptimedb:4000
jsonData:
timeField: "timestamp"
version: "latest"
四、运维操作指南
1. 日常监控
sql
SELECT
mem_used / mem_total AS mem_ratio,
cpu_usage
FROM system_metrics
WHERE region='cn-east-1'
2. 数据备份
方案:
bash
greptime --host= --query "COPY (SELECT * FROM logs) TO 'logs.csv'"
bash
# 1. 创建快照
curl -X POST http://:3002/v1/snapshot
# 2. 备份S3/HDFS
aws s3 sync /var/lib/greptime/snapshots s3://backup-bucket
3. 安全加固
措施:
yaml
# greptime.toml
[security]
# 启用TLS
tls_mode = "require"
cert_file = "/path/to/server.crt"
key_file = "/path/to/server.key"
# 访问控制
[[user]]
username = "grafana_rw"
password = "encrypted_password"
permissions = ["read", "write"]
4. 扩容操作
垂直扩容:
bash
# 修改部署配置(K8s示例)
resources:
limits:
cpu: 8
memory: 32Gi
水平扩容:
bash
greptime --start meta --node-id=3 --addr=0.0.0.0:3002
sql
ALTER TABLE logs REBALANCE PARTITIONS;
5. 告警通知管理
日常操作:
bash
# 查看活泼告警
curl -u admin:password http://grafana:3000/api/v1/alerts
# 测试通知通道
curl -X POST http://grafana:3000/api/v1/notifications/test/wecom-notifier
灾难恢复增强:
图表
安全加固补充
在原有安全配置中增加:
yaml
# greptime.toml
[security.alert_auth]
# 告警API访问控制
wecom_key = "encrypted_xxxxxxxx"
dingding_token = "encrypted_xxxxxxxx"
告警模块注意事项
sql
ALTER TABLE alerts ADD DEDUP KEY(alert_name, instance);
yaml
# otel-collector-config.yaml
processors:
redaction:
patterns: ["password=\\w+", "token=[a-f0-9]{32}"]
yaml
# Grafana告警规则
- alert: 节点故障
...
annotations:
# 限定相同告警每30分钟通知一次
repeat_interval: 30m
图表
故障恢复验证流程
bash
# 触发写入延迟
stress-ng --cpu 8 --io 4 --timeout 300s
