requirement

I have a YAML File whose content looks like below.

http_port: 8000
frequency: 60

applications:
  - name: TOP
    command: gxrun TOP gx_watch
  - name: GCSS
    command: gxrun GCSS gx_watch

Now I need a python script, that is compatible with python 2.7 version and it should not have any dependencies on the third party libraries. I only have those libraries that come by default with python 2.7. 

The python script must execute the commands that i will be listing in the yaml file and parse the output line by line and expose the metrics as I have explained below.

the yaml will be present in location /opt/apps/gxadm/xtest/tuxedo_monitor_config.yaml

the python script keep exposing continuously the metrics in prometheus format at a HTTP endpoint at the port that is specified in the yaml file and at the frequency mentioned in the yaml file. 
If no port or frequency is specified in yaml file, then default port must be 8000 and default frequency must be 60 and please frequency will be in seconds.

Now coming to logic for capturing the metrics by parsing the output of the command..

if the line is similar to this pattern : Normal: comp=TOP All 10 Tuxedo processes are running

then parse as below..

tuxedo_process_status = Normal [ 2 if Normal, 1 if critical and 0 if anything else) ==> this should be the metric
tuxedo_running_process = 10 ==> this should be the metric
tux_comp = TOP  ==> This should be a label for metrics tuxedo_process_status, tuxedo_running_process
tux_process_status_message = All 10 Tuxedo processes are running

If the line similar to this pattern: Normal: comp=TOP all proxies are running

tuxedo_proxy_status = Normal [ 2 if Normal, 1 if critical and 0 if anything else] ==> this should be a metric
tux_comp = TOP [ this is similar to the label I mentioned above] ==> this should be a label for tuxedo_proxy_status metric
tux_proxy_status_message = all proxies are running ==> this should be a label for tuxedo_proxy_status metric

if the last part of the line is 'all proxies are running' then,

tuxedo_missing_proxies = 0  ==> this should be metric [ Labels with this metric are tux_comp, tux_proxy_status_message]

or if the last part of the line is '10 proxies missing' then,

tuxedo_missing_proxies = 10 ==> this should be a metric [ Labels with this metric are tux_comp, tux_proxy_status_message]


if the line is similar to this pattern: Normal: all proxies are running
tuxedo_proxy_status = Normal [ 2 if Normal, 1 if critical and 0 if anything else] ==> this should be a metric
tux_comp value should be exactly same as it is for for tux_comp label that is part of tux_process_status metric
tuxedo_missing_proxies = 0 ==> this should be metric
tux_proxy_status_message = all proxies are running ==> this should be a label

if the line is similar to this pattern: Critical: 8 proxies are running
tuxedo_proxy_status = Critical [ 2 if Normal, 1 if critical and 0 if anything else] ==> this should be a metric
tux_comp value should be exactly same as it is for for tux_comp label that is part of tux_process_status metric
tuxedo_missing_proxies = 8 ==> this should be metric
tux_proxy_status_message = 8 proxies are running ==> this should be a label

Ignore any other line from the output of the command you execute..

Please note that I will run this python script as daemon.
