Working in docker

metal-scrapper is a tool to collect machine metrics and flush it to clickhouse. To run docker container execute:

docker run -d --name metal \
    -v /proc:/hostproc \
    -v /docker-data/metal_config.yml:/metal-config.yml \
    -e CONFIG=/metal-config.yml \
mrandersen7/metal:1.5

Configs

This will volume your configuration file and use it to run the daemon. Example config is located in example.yml

• proc_locaton - where linux proc directory located (volumed)
• hostname - hostname of machine which will be inserted into CH
• verbosity - verbosity of log output (2 - all, 1 - partly, 0 - none)
• buffer.flush_period - flush period in ms
• clickhouse - section for clickhouse connection.
• collector_memory.period - for each collector - u can specify aggregation interval in ms, for full name list - see example.yml

After program will be launched - it will create 2 tables to store float and string metric values separated in your clickhouse connection in default database, after that u can aggregate them via grafana, or any other tools

Metrics

• metal_scrapper_current_rss_bytes - current memory usage for metal-scrapper
• cpu_load_1 - load average 1 min

• cpu_load_15 - load average 15 min
• cpu_ps_count - current process count
• hdd_total_bytes - total bytes at / filesystem
• hdd_free_bytes - free bytes at / filesystem
• memory_total_bytes - total bytes of memory
• memory_free_bytes - available bytes of memory
