Description
WMI Poller
Known Issues
- Under heavy dev, try at your own risk. That said, it doesn't do any irreversible data changes in Observium, so it's mostly harmless
- For wmi-common there are conflicts with existing SNMP pollers
- Event logs will show several entries for updated OS, possibly processor
- Consequently, generic info is still a work in progress
- MS SQL is still a work in progress, suggestions for counters welcome
- App definitions need to be added for MS SQL (only affects Apps overview page, ie. http://yourobserviumsite/apps/app=mssql/)
- App definitions need to be revisited for Exchange
- Display name option for apps has not been added to all areas where app_type is used
Database changes
update/101.sql
- Alters applications table: adds "app_name" column
- This allows customized app name display in HTML elements such as navbars
Changes to existing files
includes/defaults.inc.php
- Added config variable for WMIC executable directory
- Added config variables for WMI polling options
- Added WMI poller modules entries, default set to 0
includes/definitions/apps.inc.php
- Added app definition for Exchange
html/pages/device/appcs.inc.php
- Fixed bug where all instances of an application would be active on navbar (
OBSERVIUM-515) - Changed app navbar to display an application name (see DB changes)
- Changed app navbar to display app instance in parenthesis
Additions
- Three WMI poller modules that must be enabled in a device's modules page
WMI Poller for Generic Server Info

wmi-005.patch
wmi-006.patch
SHOULD work with Ubuntu+ svn patch
Additions
- Added CPU usage for MSSQL process
Changes
- Aesthetic enhancements
- Added memory cache to MSSQL
- Renamed 101.sql -> 103.sql to keep up with committed SQL updates
wmi-004.patch
Additions
- Added WMI "modules" to config
- Added control over which WMI modules are polled to the WMI section in the device edit page
- Created directories:
- includes/polling/storage
- Added files:
- includes/polling/os/wmi.inc.php
- includes/polling/processors/wmi.inc.php
- includes/polling/storage/wmi.inc.php
Changes
- Reverted back to a single global poller module that includes module files
- WMI Poller will check if a WMI module is enabled in config and device_attribs before polling
- Changed $config to $GLOBALS['config']
- Moved files:
- includes/polling/storage-hrstorage.inc.php => includes/polling/storage/hrstorage.inc.php
- Changed includes/polling/storage.inc.php to reflect above
- Various optimizations, less DB queries
Mostly bug fix or two and a couple optimizations.. not much progress made.
wmi-003.patch
Changes
- Fixed device edit page for WMI
- Did not limit jQuery scope to #edit, it was disabling all form elements on page (search bar)
- wmi_query() no longer queries the database for override status for every query. Override status is queried at the beginning of each WMI module and all values are passed to wmi_query()
- Removed $config['rrd']['rra'] from rrdtool_create() calls
- MS SQL app page will look more like a device overview page whenever I figure out WTF I'm even doing
Additions
- WMI storage polling
- Requires initial discovery and poll with SNMP
- Auto-disables storage poller module
- Updates RRD and database entries created via storage poller module
- MS SQL memory
Removed
- Exchange definition in includes/definitions/apps.inc.php - Currently reviewing which graphs should be displayed on Apps page
wmi-002.patch
Changes
- Added device edit page for WMI
- wmi_query() checks for WMI override values for device and uses them if override is set to true/on
Forgot to mention under Known Issues:
- Logical disk poller only displays information and doesn't update any RRDs. It conflicts too much with the SNMP storage poller module.
Patch 006 is now in SVN.
