2017-07-09 - Version 2.6 released

This release is a minor release that fix some issues reported by
users over past year but it also adds some new interesting reports:

  • Add report on prepared transaction and oldest one in seconde per database.
  • Detect partitions and summarize information in a dedicated report.
  • Add kernel scheduler configuration for sched_autogroup_enabled and sched_migration_cost_ns to sysinfo report.
  • Add report of configuration files changes in incremental mode.
  • Report on cancelled queries due to conflicts is now a time based graph instead of a pie chart.
  • bgwritter buffer clean, checkpoint and backend statistics are now reported as bytes using size of 8192 per buffer.
  • Add report of allocated buffers with bgwritter buffer statistics.
  • Add report of transaction throughput per second.
  • Show data checksum status.
  • Add report of unlogged tables. Database with unlogged tables will be listed in cluster view.
  • Add hourly index when --rotate-hourly is enabled.

and useful features:

  • Compatibility with PostgreSQL 10.0
  • Add static index on main directory with incremental report to link to the different days.
  • Use bootstrap modal dialog windows to download graph as png.
  • Autodetect interval between collected data to support interval change during stats collect.
  • Replace javascript call to dateToDisplay.toGMTString() with dateToDisplay.toString(). Please note that this could not be backward compatible with your previous timezone settings. See pgcluu.js to revert the function call.
  • Create DDL of missing index concurrently.

Here are the complete list of bug fixes in this release:

  - Finalize systemd unit files. pgcluu_collectd.service is used to
    start pgcluu_collectd in daemon mode. Other files, pgcluu.service
    and pgcluu.timer to execute pgcluu periodically to generate reports.
  - Add import of missing jqplot.canvasAxisLabelRenderer.min.js file used
    to render axis labels in graphs.
  - Set logo and icon on a single line in an url attribute as chrome
    complain that it will be obsolete in M60.
  - Add partitioning report and partition information into cache.
  - Add hourly index when --rotate-hourly is enabled.
  - Add support of partition information to cache mode.
  - Fix unwanted exit in cache mode
  - Cosmetic change in tooltip and download button. Main menu font size have also been improved.
  - Update generated html to use Bootstrap 3 glyphicons.
  - Add javascript and CSS sources, licences and download information for
    packaging. Add a tool to minified and embedded the script and css into
    pgcluu Perl script and copy the minified files into cgi-bin/rsc/
  - Add minified resources file for CGI into cgi-bin/rsc
  - Fix redundant index query. Thanks to Julien Rouhaud for the patch.
  - Detect partitions and summarize information in a dedicated report.
    Thanks to Julien Rouhaud for the patch.
  - Refactor pidfile unlink handling. Thanks to Julien Rouhaud for
    the patch.
  - Limit call to pg_relation_size() when we are in capture mode.
    Thanks to Guillaume Lelarge for the report.
  - Add information about recheck of redundant index with primary key
    and index on a column referencing a foreign key.
  - Fix exclusion of UNIQUE index in redudant indexes report.
  - Fix incremental global index on resize.
  - Update year in copyright.
  - Add index on main directory with incremental report to link to
    the different days. Thanks to Heath Yob for the feature request.
  - Add verification that pg_stat_statement is loaded from
    shared_preload_libraries.
  - Fix incomplete per-database-statistics. Thanks to Markus Braunig
    for the report.
  - Add kernel scheduler configuration for sched_autogroup_enabled
    and sched_migration_cost_ns to sysinfo report. Thanks to Adrien
    Nayrat for the patch.
  - Fix broken main menu when no disk devices was present in sar
    report.
  - Allow to set label for y2axis in create_linegraph() parameters
  - Change parameters and return of the get_diff() method to support
    incremental mode.
  - Create function get_diff() and shows_diff() to report
    configuration file change.
  - Append new color for line graph.
  - Set missing database list with sysinfo and about menu.
  - Fix Not a HASH reference in function reporting information about
    indexes.
  - Rename diff storage variables and stores them in binary file.
    Initialyze storage variables for statistics that must be read
    from file each time.
  - Fix detection of working directories with dates over two months.
  - Fix runqueue size report. Thanks to Thomas Reiss for the report.
  - Create function to reuse the look for sysinfo file.
  - pgcluu CGI now append new csv statistic to cached binary files.
  - The menu is now built at end to avoid reading csv files first to
    look for database, disk device and network interface.
  - The CGI home page is now just built from the binary files to
    speed up the first screen. As we do not append last data collected
    from the csv files we indicate at which time the cache was last
    built. This is to give a quick snapshot of the dashboard. When
    looking at the statistics binary and csv files are both read.
    If the cache have not been run yet, pgcluu will read dashboard
    statistics from data fileis which takes longer to display.
  - Allow incremental cache. When running in cache mode pgcluu will
    append new csv statistics to old cached binary files. Then when
    building reports, pgcluu will first load statistics from binary
    files and complete statistics with data from csv file collected
    after the last cache mode run. This mean that if cache mode is
    run each minute on an incremental statistics collect (see option
    -r or -R of pgcluu_collectd), pgcluu is able to create report very
    quickly at any time. This is especially useful with CGI mode where
    a full day statistics report can be displayed in few seconds.
  - Fix diff of configuration files, old and new files was inversed.
    Thanks to Adrien Nayrat for the report.
  - Fix display of message no dataset on empty graphs.
  - Update description of temporary files report and statistics
    on checkpoints.
  - Rewrite use of interval between collected data to support change
    during collecting. Interval is now always calculated from the
    difference between the current line end the previous line. This
    mean that the first line is never present in reports with per
    second statistics.
  - Fix formatting of bytes in pretty number.
  - Improve storage of database list with huge number of database.
  - Fix timezone on all reports and remove graph per tablespace and
    replace them with a list of tablespace and their location.
  - Fix timezone on start and end timestamp of collect. Remove graph
    per tablespace and replace them with a list of tablespace and
    their location.
  - Clear Start/End input box at startup in CGI.
  - Comment and include REVERT_DATE toogle about sar date format
    in CGI configuration file.
  - Fix timezone and time selector in javascript menu.
  - Fix use of timezone and date detection in sa file.
  - Fix date parsing from sa text file.
  - Fix some warning about use of undefined variables.
  - Add link to last known statistics in CGI front page when no
    data are found.
  - Fix a call to timegm_nocheck()
  - Split set_overall_stat_from_binary() in two function, one for
    database orverall statistics and the other for system statistics.
  - Fix parsing of sa file.
  - Do not load statistic from the last day when hour:min is 00:00.
  - Fix some bugs when there is just sar cached binary files.
  - Fix two digit in date parts on start/end date.
  - Fix cache mode when there is just sar file in entry.
  - Add INCLUDE_DEV configuration directive to be able to filter
    disk device. Allow comma as list separator in configuration file.
  - Add information about how to parse sysstat sa binary and text file.
  - Fix remove of unlogged tables following pg version.
  - Fix colspan on unlogged table report.
  - Add report of transaction throughput per second.
  - Use psql -X option so .psqlrc doesn't get in the way. If .psqlrc
    contains for example \timing, pgcluu_collectd will get confused.
    Thanks to Christoph Berg for the patch.
  - Separate svctm/await dataset on two different axes.
  - Remove unwanted bgwriter stats prior pg 9.1
  - Add data checksum status to CGI report.
  - Fix autodetection of timezone and set default timezone for sar
    statistics to the result of
	perl -MPOSIX -e "print substr(strftime(\"%z\", localtime()), 0, 3);".
  - Replace javascript call to dateToDisplay.toGMTString() with
    dateToDisplay.toString(). Please note that this could not be
    backward compatible with your previous timezone settings. See
    pgcluu.js to revert the function call.
  - Fix an issue with --from-sa-file where date was still incremented.
    Thanks to Flavie Perette for the report.
  - Replace sadf -D option by -d to obtain a compatible output.
  - Separate svctm/await dataset on two different axes to be able to
    see both dataset.
  - Fix kernel parameter hugepage report when not available.
  - Fix all call of psql that use both -f - and -c that doe not have
    the same behavior in pg 9.6. Previous version does not care of
    the -f stdin input when a command was provided with -c. This not
    compatible anymore. Thanks to Vincent Laborie for the report.
  - Fix collect of lock in pg_stat_activity with PostgreSQL 9.6.
    Thanks to Vincent Laborie for the report.
