I am trying to create a dictionary using data produced by a
load balancing admin tool and aggregate the results. When I invoke the tool from within the shell (‘sudo
~/ZLBbalctl --action="" the following output is produced: Load Balancer 1 usage, over the last 30 seconds Port 80, rules - /(nol)|(ws) server001 alive 18.1% 2 requests/s 14536543
total server002 alive 43.1% 7 requests/s 14842618
total server003 alive 21.2% 2 requests/s 14884487
total server004 alive 17.3% 2 requests/s 15092053
total Load Balancer 2 usage, over the last 30 seconds Port 80, rules - /(nol)|(ws) server001 alive 11.6% 2 requests/s 14482578
total server002 alive 35.6% 9 requests/s 14820991
total server003 alive 28.7% 6 requests/s 14928991
total server004 alive 23.7% 5 requests/s 15147525
total I have managed to get something close to what I’m
looking for using lists i.e. the aggregate of the fourth column (requests/s) lbstat = commands.getoutput("sudo ~/ZLBbalctl
--action="" | awk '$1 ~ /^server00/ { print $4 }'") rLst = lbstat.split('\n') rLst = [ int(rLst[i]) for i in range(len(rLst)) ] rTotal = reduce(operator.add, rLst) However here’s what I’m now trying to do: 1) Not have to
rely on using awk at all. 2) Create a
dictionary with server names for keys e.g. server001, server002 etc and the aggregate
of the request for that server as the value part of the pairing. I got this far with part 1) lbstat = commands.getoutput("sudo ~/ZLBbalctl --action=""> tmpLst = lbstat.split('\n') rLst = [] for i in tmpLst: m =
re.search('
server[0-9]+', i) if m: rLst.append(i) for i in rLst: print i, type(i) server001 alive 22.3% 6 requests/s 14527762
total <type 'str'> server002 alive 23.5% 7 requests/s 14833265
total <type 'str'> server003 alive 38.2% 14 requests/s 14872750 total
<type 'str'> server004 alive 15.6% 4 requests/s 15083443
total <type 'str'> server001 alive 24.1% 8 requests/s 14473672
total <type 'str'> server002 alive 23.2% 7 requests/s 14810866
total <type 'str'> server003
alive 30.2% 8 requests/s 14918322
total <type 'str'> server004 alive 22.1% 6 requests/s 15137847
total <type 'str'> At this point I ran out of ideas and began to think that
there must be something fundamentally wrong with my approach. Not least of my
concerns was the fact that I needed integers and these were strings. Any help would be much appreciated. Regards, Paul |
