Currently can find the SNMP Expoter version via commands

[houchunzhong]

the SNMP agent devcies are compose of Huawei S6700 and S5700 switches and AR3200 routers. I upload them to the mibs, but when using SNMP generator to build, it seems the snmp.yml file doesn't consist Huawei OIDs infor. Please elighten me to find a path the go through.

When using SNMP expoter ,huawei switch is able to reponse with OIDs query results.

the proemethemus.yml configured as below:

my global config

global:
scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.

scrape_timeout is set to the global default (10s).

Alertmanager configuration

alerting:
alertmanagers:

• static_configs:
  • targets:

    - alertmanager:9093

Load rules once and periodically evaluate them according to the global 'evaluation_interval'.

rule_files:

- "first_rules.yml"

- "second_rules.yml"

A scrape configuration containing exactly one endpoint to scrape:

Here it's Prometheus itself.

scrape_configs:

The job name is added as a label job=<job_name> to any timeseries scraped from this config.

• job_name: 'prometheus'

  metrics_path defaults to '/metrics'

  scheme defaults to 'http'.

  • targets: ['10.28.119.205:9090']
