Skywalking对主机，数据库等系统状态提供了全面的监控，这里来演示下如何进行接入，仅做参考！
1. 监控主机状态
1.1 部署Prometheus node-exporter
# 请自行部署
1.2 安装OpenTelemetry Collector
1.2.1 创建文件夹
root@ubuntu2204test99:~# mkdir -p OpenTelemetryCollector/config
1.2.2 编写docker-compose
root@ubuntu2204test99:~/OpenTelemetryCollector# cat docker-compose.yml
services:
otel-collector:
image: otel/opentelemetry-collector-contrib:0.50.0
command: [ "--config=/etc/otel-collector-config.yaml" ]
volumes:
#- ./config/otel-collector-config.yaml:/etc/otelcol-contrib/config.yaml
- ./config/otel-collector-config.yaml:/etc/otel-collector-config.yaml
ports:
#- 1888:1888 # pprof extension
#- 28888:8888 # Prometheus metrics exposed by the Collector
#- 28889:8889 # Prometheus exporter metrics
#- 13133:13133 # health_check extension
#- 4317:4317 # OTLP gRPC receiver
#- 4318:4318 # OTLP http receiver
- 55678:55678 # zpages extension
1.2.3 修改配置文件
root@ubuntu2204test99:~# cat OpenTelemetryCollector/config/otel-collector-config.yaml
receivers:
prometheus:
config:
scrape_configs:
- job_name: "vm-monitoring" # make sure to use this in the vm.yaml to filter only VM metrics
scrape_interval: 10s
static_configs:
- targets: ["192.168.1.98:9100"]
processors:
batch:
exporters:
otlp:
endpoint: "192.168.1.99:11800" # The OAP Server address
# The config format of OTEL version prior to 0.34.0, eg. 0.29.0, should be:
# insecure: true
tls:
insecure: true
#insecure: true
# Exports data to the console
logging:
loglevel: debug
service:
pipelines:
metrics:
receivers: [prometheus]
processors: [batch]
exporters: [otlp, logging]
2. 监控mysql状态
2.1 部署mysql-exporter
# 请自行部署
2.2 修改OpenTelemetry配置
root@ubuntu2204test99:~# cat OpenTelemetryCollector/config/otel-collector-config.yaml
receivers:
prometheus:
config:
scrape_configs:
- job_name: "vm-monitoring" # make sure to use this in the vm.yaml to filter only VM metrics
scrape_interval: 10s
static_configs:
- targets: ["192.168.1.98:9100"]
# 监控Mysql示例
- job_name: "My-DB-Serv" #注意这个名称
scrape_interval: 5s
static_configs:
- targets: ["192.168.1.43:9105"]
labels: #标签会影响在Skywalking中显示的名字
#host_name: root[root]
host_name: My-DB[192.168.1.43]
processors:
batch:
exporters:
otlp:
endpoint: "192.168.1.99:11800" # The OAP Server address
# The config format of OTEL version prior to 0.34.0, eg. 0.29.0, should be:
# insecure: true
tls:
insecure: true
#insecure: true
# Exports data to the console
logging:
loglevel: debug
service:
pipelines:
metrics:
receivers: [prometheus]
processors: [batch]
exporters: [otlp, logging]
2.3 修改Skywalking中mysql的相关配置
root@ubuntu2204test99:~/skywailking# vi skywalking-oap/config/otel-rules/mysql/mysql-instance.yaml
#filter: "{ tags -> tags.job_name == 'mysql-monitoring' }" # The OpenTelemetry job name
filter: "{ tags -> tags.job_name == 'HK-DB-Serv' }" # 要和otlp配置的job_name匹配
.........
root@ubuntu2204test99:~/skywailking# vi skywalking-oap/config/otel-rules/mysql/mysql-service.yaml
#filter: "{ tags -> tags.job_name == 'mysql-monitoring' }" # The OpenTelemetry job name
filter: "{ tags -> tags.job_name == 'HK-DB-Serv' }" # 要和otlp配置的job_name匹配
.........
