The hc is lightweight health checker written in php. hc can check health of http services, popular databases (mysql, postgres) and redis. Default output format is tab-delimited strings to allow easily grep and cut results.

1. Create config file config.yml with check rules:

   ---
   - name: google
     type: http
     request: { url: http://google.com/ }
     
   - name: bing
     type: http
     request: 
       url: http://bing.com:1234/
       timeout: 1
   

2. Run hc:

   hc config.yml
   

   You should see result (tab-delimited):

   ok	google
   fail	bing	connection refused
   

hc [-th] [-o format] <config-file> 

• -h: print command help and list of available assertions;
• -t: don't run, just test the configuration file;
• -o format: set format of output; default is "tsv". Allowed: "tsv", "json".

See descriptive examples of configuration file and output in examples directory.
