tracking databases that do not have autogrowth enabled. The counters return numbers in 8KB pages since there are a few special values (such as -1 for no max size) that can't directly be multiplied by 8192 to get size in bytes. Also added Rows/Logs size in 8KB pages for comparison from the same system table. Even though it returns the same size as sizes from sys.dm_io_virtual_file_stats which are already collected. --- plugins/inputs/sqlserver/sqlserver.go | 46 +++++++++++++++++++++++++++ 1 file changed, 46 insertions(+) diff --git a/plugins/inputs/sqlserver/sqlserver.go b/plugins/inputs/sqlserver/sqlserver.go index f91e66c24..5b754d772 100644 --- a/plugins/inputs/sqlserver/sqlserver.go +++ b/plugins/inputs/sqlserver/sqlserver.go @@ -400,6 +400,8 @@ IF OBJECT_ID('tempdb..#baseline') IS NOT NULL DROP TABLE #baseline; SELECT DB_NAME(mf.database_id) AS database_name , + mf.size as database_size_8k_pages, + mf.max_size as database_max_size_8k_pages, size_on_disk_bytes , type_desc as datafile_type, GETDATE() AS baselineDate @@ -435,6 +437,50 @@ FROM #baseline WHERE datafile_type = ''ROWS'' ) as V PIVOT(SUM(size_on_disk_bytes) FOR database_name IN (' + @ColumnName + ')) AS PVTTable + +UNION ALL + +SELECT measurement = ''Rows size (8KB pages)'', servername = REPLACE(@@SERVERNAME, ''\'', '':''), type = ''Database size'' +, ' + @ColumnName + ' FROM +( +SELECT database_name, database_size_8k_pages +FROM #baseline +WHERE datafile_type = ''ROWS'' +) as V +PIVOT(SUM(database_size_8k_pages) FOR database_name IN (' + @ColumnName + ')) AS PVTTable + +UNION ALL + +SELECT measurement = ''Log size (8KB pages)'', servername = REPLACE(@@SERVERNAME, ''\'', '':''), type = ''Database size'' +, ' + @ColumnName + ' FROM +( +SELECT database_name, database_size_8k_pages +FROM #baseline +WHERE datafile_type = ''LOG'' +) as V +PIVOT(SUM(database_size_8k_pages) FOR database_name IN (' + @ColumnName + ')) AS PVTTable + +UNION ALL + +SELECT measurement = ''Rows max size (8KB pages)'', servername = REPLACE(@@SERVERNAME, ''\'', '':''), type = ''Database size'' +, ' + @ColumnName + ' FROM +( +SELECT database_name, database_max_size_8k_pages +FROM #baseline +WHERE datafile_type = ''ROWS'' +) as V +PIVOT(SUM(database_max_size_8k_pages) FOR database_name IN (' + @ColumnName + ')) AS PVTTable + +UNION ALL + +SELECT measurement = ''Logs max size (8KB pages)'', servername = REPLACE(@@SERVERNAME, ''\'', '':''), type = ''Database size'' +, ' + @ColumnName + ' FROM +( +SELECT database_name, database_max_size_8k_pages +FROM #baseline +WHERE datafile_type = ''LOG'' +) as V +PIVOT(SUM(database_max_size_8k_pages) FOR database_name IN (' + @ColumnName + ')) AS PVTTable ' --PRINT @DynamicPivotQuery EXEC sp_executesql @DynamicPivotQuery; From 3098564896c6cca7ba7e12745732670e109f6bae Mon Sep 17 00:00:00 2001 From: Konstantin Kulikov Date: Fri, 17 Jun 2016 23:14:29 +0300 Subject: [PATCH 018/120] fix datarace in input apache plugin closes #1384 --- CHANGELOG.md | 1 + plugins/inputs/apache/apache.go | 14 ++++++++------ plugins/inputs/apache/apache_test.go | 3 ++- 3 files changed, 11 insertions(+), 7 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 543bea055..e7e38c704 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -21,6 +21,7 @@ -

This is useful -in conjunction with wildcard dimension values as it will control the amount of -time before a new metric is included by the plugin. - -### Features - - [#1262](https://github.com/influxdata/telegraf/pull/1261): Add graylog input pluging. - [#1294](https://github.com/influxdata/telegraf/pull/1294): consul input plugin.

Updated windows dependencies Updated the windows dependencies so that the versions matched the dependencies for Mac OS and Linux. Additionally added some that were complained about being missing at compile time. Incorporated kardianos/service for management Incorporated the library github.com/kardianos/service to manage the service on the various platforms (including Windows). This required an alternate main function. The original main function was renamed to reloadLoop (as that is what the main loop in it does) (it also got a couple of parameters). The service management library calls it as the main body of the program. Merged service.go into telegraf.go Due to compilation issues on Windows, moved the code from service.go into telegraf.go and removed service.go entirely. Updated dependencies and fixed Windows service Updated the dependencies so that it builds properly on Windows, additionally, fixed the registered command for starting it as a service (needed to add the config file option). This currently standardizes it as a C:\telegraf\telegraf.conf on Windows. Added dependency for github.com/kardianos/service Removed the common dependencies from _windows file Removed all the common dependencies from the Godeps_windows file and modified Makefile to load Godeps and then Godeps_windows when building for Windows. This should reduce problems caused by the Godeps_windows file being forgotten when updating dependencies. Updated CHANGELOG.md with changes Ran `go fmt ./...` to format code Removed service library on all but Windows The service library [kardianos/service](github.com/kardianos/service) has been disabled on all platforms but windows, as there is already existing infrastructure for other platforms. Removed the dependency line for itself It appears that gdm accidentally added the project itself to the dependency list. This caused the dependency restoration to select an earlier version of the project during build. This only affected windows. This only affected builds after 020b2c70 Updated documentation for Windows Service Removed the documentation about using NSSM and added documentation on installing telegraf directly as a Windows Service. Added license info for kardianos/service Added the license information for github.com/kardianos/service which is licensed under the ZLib license, although that name is never mentioned the license text matches word for word. Changed the Windows Config file default location Updated the default location of the configuration file on Windows from C:\telegraf\telegraf.conf to C:\Program Files\Telegraf\telegraf.conf. With this change includes updating the directions, including directing that the executable be put into that same directory. Additionally, as noted in the instructions, the location of the config file for the service may be changed by specifying the location with the `-config` flag at install time.

function to generate source The change is made that it should be retro compatible Metric sample: server=127.0.0.1 port=80 state=leader env=test measurement.metric_name value service_n.metric_x Metric

measurement.metric_name service_n.metric_x As you can see the source in the "new" version is much more precise That way when filter (only from source) you can filter by env or any other tags * Using template to specify which tagsusing for source, default concat all tags * revert change in graphite serializer * better documentation, change default for template * fmt * test passing with new host as default tags * use host tag in api integration test * Limit 80 char per line, change resolution to be a int in the sample * fmt * remove resolution, doc for template * fmt ---
