mfscsstatsdump(8) This is part of MooseFS mfscsstatsdump(8) NAME mfscsstatsdump - dump usage data from chunkserver stats file in csv or png format SYNOPSIS mfscsstatsdump -f fields [-i stats_file] [-r range][-s separator] [-p png_filename [-x chart_width] [-y chart_height]] [-hHd] DESCRIPTION mfscsstatsdump dumps usage data from chunkserver stats file. These are the same data sets that are used to make GUI charts. Output can be either in text format (csv) or in graphical format (png). That means -p, -x and -y options are mutually exclusive with -h, -H and -d options. MooseFS chunkserver saves the stats file in the DATA_PATH directory - see mfschunkserver.cfg(5) OUTPUT Text output - text (csv) file where first column is a timestamp (or date if -d option was specified), the following column are what was specified with the -f options, formatted according to used options (none, -s and -h or -H) Graphical output - one png file with a chart is created for every field specified with the -f option, according to the naming scheme declared with the -p option. Size may be adjusted with -x and -y options. OPTIONS -f field names separated by ',' (see FIELDS section); at least one field is mandatory; if an asterisk (*) is used, all fields are dumped -i name of mfs binary stats file (default: de- fault_data_path/csstats.mfs) -r range type: 0 - short range (minute) 1 - medium range (6 minutes) 2 - long range (30 minutes) 3 - very long range (day) -s specify column separator (default: tabulator) -p optional PNG filename (field name will be added before .png; YYYY -> YYYY_FIELD.png, YYYY.png -> YYYY_FIELD.png) -x PNG chart width (default: 1600) -y PNG chart height (should be divisible by 20 - if not then it will be adjusted; default:320) -h "human-readable" numbers using base 2 prefixes (IEC 60027) -H "human-readable" numbers using base 10 prefixes (SI) -d show timestamps in YYYY-MM-DD HH:MM format FIELDS ucpu User cpu usage scpu System cpu usage cpu Total cpu usage (in csv sum of scpu and ucpu, in png shows both in different colors) masterin Data received from master masterout Data sent to master csrepin Data received by replicator csrepout Data sent by replicator csservin Data received by csserv csservout Data sent by csserv bwin Data bandwidth in (in csv sum of csrepin and csservin, in png shows both in different colors) bwout Data bandwidth out (in csv sum of csrepout and csservout, in png shows both in different colors) hdrbytesr Bytes read (headers) hdrbytesw Bytes written (headers) hdrllopr Low level reads (headers) hdrllopw Low level writes (headers) databytesr Bytes read (data) databytesw Bytes written (data) datallopr Low level reads (data) datallopw Low level writes (data) hddread HDD read (in csv sum of hdrbytesr and databytesr, in png shows both in different colors) hddwrite HDD write (in csv sum of hdrbytesw and databytesw, in png shows both in different colors) hddopsr HDD low level read (in csv sum of hdrllopr and datallopr, in png shows both in different colors) hddopsw HDD low level write (in csv sum of hdrllopw and datallopw, in png shows both in different colors) hlopr High level reads hlopw High level writes rtime Read time wtime Write time repl Replicate chunk ops create Create chunk ops delete Delete chunk ops version Set version ops duplicate Duplicate ops truncate Truncate ops duptrunc Duptrunc (duplicate+truncate) ops test Test chunk ops load Server load memoryrss Resident memory usage memoryvirt Virtual memory usage mem Total memory usage (in csv is the same as memoryvirt, in png shows both memoryrss and memoryvirt using two colors) movels Low speed move ops movehs High speed move ops move Low speed + high speed move ops (in png shows movels and movehas using two colors) change Chunk changes in metadata (sum of version + duplicate + trun- cate + duptrunc + split) split Split ops usedspace Used HDD space in bytes (mark for removal excluded) totalspace Total HDD space in bytes (mark for removal excluded) space Total HDD space (in csv same as totalspace, in png shows both usedspace and totalspace using two colors) chunkcount Number of stored chunks (mark for removal excluded) tdusedspace Used HDD space in bytes on disks marked for removal tdtotalspace Total HDD space in bytes on disks marked for removal tdchunkcount Number of chunks stored on disks marked for removal copychunks Number of chunks stored in copy format (all disks) ec4chunks Number of chunk parts stored in EC4 format (all disks) ec8chunks Number of chunk parts stored in EC8 format (all disks) chunks Sum of copychunks + ec4chunks + ec8chunks (in png shows all three in different colors) hddok Number of valid folders (hard drives) hddmfr Number of folders (hard drives) that are marked for removal hdddmg Number of folders (hard drives) that are marked as damaged hddcnt Number of folders (hard drives) regardless of status, aka sum of hddok + hddmfr + hdddmg (in png shows all three in differ- ent colors) udiff Difference in usage percent between the most and least used disk REPORTING BUGS Report bugs to <bugs@moosefs.com>.
