# System Utilities
|
|
|
|
This section will describe **System Utilities** in Cacti.
|
|
|
|
The system utilities page in cacti contains tools used for administering
|
|
cacti from this page you can do the following
|
|
|
|
- Rebuild poller cache.
|
|
|
|
- View technical support information.
|
|
|
|
- Adjust log settings.
|
|
|
|
- View the user log for audits.
|
|
|
|
.
|
|
|
|
Some of the most important tools are listed below
|
|
|
|
## Rebuild poller cache
|
|
|
|
The Poller Cache will be re-generated if you select this option. Use this
|
|
option only in the event of a database crash if you are experiencing issues
|
|
after the crash and have already run the database repair tools. Alternatively,
|
|
if you are having problems with a specific Device, simply re-save that Device
|
|
to rebuild its Poller Cache. There is also a command line interface equivalent
|
|
to this command that is recommended for large systems. NOTE: On large systems,
|
|
this command may take several minutes to hours to complete and therefore
|
|
should not be run from the Cacti UI. You can simply run
|
|
'php -q cli/rebuild_poller_cache.php --help' at the command line for more
|
|
information.
|
|
|
|
### Technical support
|
|
|
|
Cacti technical support page. Used by developers and technical support
|
|
persons to assist with issues in Cacti. Includes checks for common
|
|
configuration issues. There is also built-in checks that help you tune
|
|
your Cacti installation.
|
|
|
|
For example in the technical support section under the summary, you will see a
|
|
calculation for how many MySQL connections. You should have (Cacti 1.2.16+)
|
|
you will also show poller information such as the last polling time process
|
|
count and more detailed info that can be used for a quick view of how the
|
|
system is configured.
|
|
|
|
.
|
|
|
|
You will also see all of the system variables such as allocated php memory
|
|
as well as mysql variables.
|
|
|
|
|
|
|
|
Any Variable appearing in red indicates a subpar setting and should be looked.
|
|
the recommendations are dynamic in that they change when more system resources are
|
|
detected so if you upgrade your server hardware be sure to check back to this page
|
|
to get the most out of your new hardware.
|
|
|
|
### RRD cleaner
|
|
|
|
`Console > utilities > System Utilities > RRDfile Cleaner`
|
|
|
|
When you delete Data Sources from Cacti, the corresponding RRDfiles are not
|
|
removed automatically. Use this utility to facilitate the removal of
|
|
these old files.
|
|
|
|
In system utilities you can manually start the RRD cleaning procedure
|
|
You can either archive the selected RRD's
|
|
to have them deleted in the next polling cycle
|
|
|
|
|
|
|
|
RRDfiles can also be schedule to automatically be removed this option can
|
|
be configured in `Console > Configuration > Settings > Paths` by selecting
|
|
the RRDfile autoclean selection.
|
|
|
|
|
|
|
|
### RRDfile Checker
|
|
|
|
`Console > utilities > System Utilities > RRDfile Checker`
|
|
|
|
The RRDfile checker is a tool that scans all RRDfiles at a
|
|
scheduled time and tests the stored data:
|
|
|
|
- Stale values for 1 or 24 hours
|
|
- Whether the file is updated regularly
|
|
- Incorrect file read/write access
|
|
- Whether the Database Data Source objects match the RRDfiles Data Sources
|
|
|
|
For very large Cacti installs the **RRDfile checker** can take quite
|
|
a long time to complete.
|
|
You can set number of concurrent parallel processes in `Console > Configuration > Settings > Data`
|
|
|
|
### Viewing Change log from system utilities
|
|
|
|
With Cacti 1.2.16+, you are now able to view the CHANGELOG information up to the
|
|
version your server is currently running. This is available via the system
|
|
utilities menu which is useful for seeing what fixes and occasional features are
|
|
included in your version.
|
|
|
|
|
|
|
|
### View user login history
|
|
|
|
`Console > utilities > System Utilities > View user Log`
|
|
|
|
In system utilities you are able to view a log of user logins
|
|
both successful and failures The Log will also show what Client IP address
|
|
the login originated from along with info
|
|
if the login was based on password or token based login
|
|
|
|
|
|
|
|
### View boost update status and stats

|
|

|
|
|
|
|
|
|
|
|
|
|
|
### Viewing the Data Source Query Cache
|
|
|
|
`Console > Utilities > System Utilities > View Data Source Query Cache`
|
|
|
|
The Data Query Cache stores information gathered from Data Query input types.
|
|
The values from these fields can be used in the text area of Graphs for Legends,
|
|
Vertical Labels, and GPRINTS as well as in CDEF's.
|
|
|
|
|
|
|
|
### Viewing the Poller Cache
|
|
|
|
`Console > Utilities > System Utilities > View Poller Cache`
|
|
|
|
This is the data that is being passed to the poller each time it runs.
|
|
|
|
|
|
|
|
### Viewing System log via System Utilities
|
|
|
|
You are able to view the system log via the System utilities
|
|
page this will show the RAW log
|
|
this slightly differs from the view log tab as the device names
|
|
will show the device ID rather than
|
|
the Device name this is the same view as you reading the log in the OS
