Enduro/X Core

To get screen geometry: popen (" stty size") and parse:

$ stty size
34 103

tops -s (default) by succeed count, secondary order succeed total, third order by srvid, forth order by service name
tops -f order by fail count increment, secondary order fail total, third order by srvid, forth order by service name
tops -b order by busy services, secondary order succeed total, third order by srvid, forth order by service name
tops -m -> sort by max rsp time
tops -l -> sort by last rsp time

Also we want a sorting by delta ( Success: S - Descending, s - ascending, Fail: F - descending, f - ascending)

for tops, if space allows add delta column

If particular row was present at previous scan, and missing at new scan or vice versa, then add those lines at the top. at that scan interval. So we shall show also Fails/sec, Succeed/sec

xadmin topp -> ppm monitor, watch over RSP column

should go to 5.3

So basically:

start:
- we have two hashes, current result and previous, each hash key is build accordingly, for example serverid/service_name
- create additional structure to hold the compare data
- scan current all keys to old, detect whats new here, mark records as new if needed
- scan old, detect keys missing in current, add records, mark as removed
- transfer current to linear array
- sort linear array with qsort, set the corresponding sort function
- clear screen
- get terminal x,y
- print the results (x lines, y chars)
- sleep 2 sec (from config t XXXX to override time)
free the linear array
- free previous hash
- save current hash ptr as old
- goto "start"
- at the end free up all hashes.
- allow to switch modes by background key scan (new thread, which changes the sort mode, i.e. s,f,b,m,l. This will store the letter in some global var
- if pressed "q", we should return back to terminal, background thread is killed.

We need following callback to make it "top" generic:

1. top_results_get (call corresponding services). Maybe we can re-use existing command callbacks?
2. top_results_transfer copy to hash list
3. top_get_array
4. top_sort_callback
5. top_print_hdr with snprintf(according to terminal size &buffer size)
6. top_print_data_line with snprintf (according to terminal size &buffer size)
7. top_free_hash

By pressing keys 1...9 that will set refresh seconds

version 5.4, implement for tops, topp, topc, topq
