IndexHomeThe process afd_stat is started by init_afd at startup and continues running and collects statistics as long as AFD is up and running. Should afd_stat be killed or crashes, it will always be restarted by init_afd. afd_stat stores input and output statistics in binary form in the files $AFD_WORK_DIR/log/afd_istatistic_file.2006 and AFD_WORK_DIR/log/afd_statistic_file.2006 respectively. Where the number 2006 is the current year of the system. For each new year afd_stat will create new input and output statistics files. So the old ones will not be deleted.
For the input statistic the database will hold the values: number of files received and the number of bytes received. The output statistic database holds the the number of files send, number of bytes send, the number of network connections and the number of errors that have occurred. All those values are stored on a hourly, daily and year basis. Where the hour holds values in 5 second interval (that is 720 values per hour), the day holds 24 hours and the year 365 (or 366) days.
To view the binary statistic files there are two command line tools: show_istat (input) and show_stat (output). These tools will round the number of bytes send or received according the following table:
| Value in bytes | Symbol used | Description |
|---|---|---|
| < 1024 | B | Bytes |
| < 1048576 | KB | Kiloytes |
| < 1073741824 | MB | Megaytes |
| < 1099511627776 | GB | Gigabytes |
| < 1125899906842624 | TB | Teraytes |
| < 1152921504606846976 | PB | Petabytes |
| < 1180591620717411303424 | EB | Exabytes |
The command line program show_istat can take the following parameters:
SYNTAX : show_istat [options] [dir 1 ....]
-w <work dir> Working directory of the AFD.
-f <name> Path and name of the statistics file.
-d [<x>] Show information of all days [or day minus x].
-D Show total summary on a per day basis.
-h [<x>] Show information of all hours [or hour minus x].
-H Show total summary of last 24 hours.
-mr <x> Show summary of last x minutes.
-m [<x>] Show information of all minutes [or minute minus x].
-M [<x>] Show total summary of last hour.
-t[u] Put in a timestamp for when this output is valid.
-T Show numeric total only.
-y [<x>] Show information of all years [or year minus x].
--version Show current version.
To view the statistics for the last 24 hours use show_istat -H. This will produce the following output:

The * is for the current hour. The meaning of this line is first the hour, then the number of files received and last the number of bytes received. Similar input statistics can be shown for the last 60 minutes (-M) and the last 365 days (-D).
To view for example the last 5 minutes use the parameter -mr 5:

There are numerous other options like -T, which will only show numeric totals or -y to view statistics of a specific year. Best is to just try out the different options.
There is a similar command line program show_stat for viewing output statistics that can take the following parameters:
SYNTAX : show_stat [options] [hostname 1 ....]
-w <work dir> Working directory of the AFD.
-f <name> Path and name of the statistics file.
-d [<x>] Show information of all days [or day minus x].
-D Show total summary on a per day basis.
-h [<x>] Show information of all hours [or hour minus x].
-H Show total summary of last 24 hours.
-mr <x> Show summary of last x minutes.
-m [<x>] Show information of all minutes [or minute minus x].
-M [<x>] Show total summary of last hour.
-t[u] Put in a timestamp for when this output is valid.
-T Show numeric total only.
-y [<x>] Show information of all years [or year minus x].
--version Show current version.
To view the statistics for the last 24 hours use show_stat -H. This will produce the following output:

Again the first number is the hour, followed by the number of files send, the number of bytes send, the number of connections and last the number of errors encountered. Similar output statistics can be shown for the last 60 minutes (-M) and the last 365 days (-D).
To view for example the last 5 minutes use the parameter -mr 5:
