Title: Graphs: Vertical axis scaling and mirroring can now be customized
Component: Multisite
Level: 2
Class: New feature
Version: 1.5.0i1
You can now customize the vertical axis scaling mode and mirror the
metrics in a graph if you like. This can be done just for yourself
or for all your users.
This can be useful, for example, if you like to change the scaling
of all CPU usage graphs from fixed 100% to dynamical scaling based
on the measured values.
This feature is usable for all template based and combined graphs.
It does not affect custom graphs at all.
To configure such a customization open your GUI and click the {{Edit}}
button of your {{Views}} snapin. Then click on the {{Graph tunings}}
button on the top of the page. From this page you can then create a
new graph tuning where you first need to set a title and the graph
type you want to customize

Title: Fixed timeouts when generating reports (regression in #4957)
Component: Reporting & Availability
Level: 2
Class: Bug fix
Version: 1.5.0i1
When creating PDF reports that contain grouped view elements, these
reports were rendering too many data. In case of larger reports with
a lot of graphs, this could lead to timeouts resulting in "Proxy Errors"
messages in the GUI.
This issue was introduced with werk 4957 since Check_MK 1.4.0p9.

Title: Check_MK HW/SW Inventory: The service was executed too often by default
Component: HW/SW Inventory
Level: 2
Class: Bug fix
Version: 1.5.0i1
Issue: The HW/SW inventory may produce a lot of load because of wrong scheduling.
You may be affected by this bug in case you created your (master) site with 1.4.0b1
or newer. If you updated your site from older versions you are likely not affected.
Slave sites that get their configuration from a master that is not affected will also
not be affected, regardless of the version they were created with.
When using the hardware software inventory the regular check "Check_MK HW/SW Inventory"
on each host is executed too often by default. The expected behaviour is that the regular
check interval of this service is 1 day. The bug we fixed now made the check being executed
once a minute. In case you have the HW/SW inventory enabled for a lot of hosts, this could
lead to significant load on your Check_MK server.
Whether or not you have this issue can be checked on the "service detail" page of the
"Check_MK HW/SW Inventory" service. Have a look at the "Service normal/retry check interval"
column where you should see 86400s as first value (-> 1 day). If you see a value of 60s, you
should fix the issue as follows.
<ul>
<li>Navigate to "WATO > Host & Service parameters > Monitoring configuration > Normal check
interval for service checks".</li>
<li>Create a new rule with the following settings:</li>
<li>Description: Restrict HW/SW-Inventory to once a day</li>
<li>Value: 1 day</li>
<li>Services: <tt>Check_MK HW/SW Inventory$</tt></li>
<li>Activate the changes via WATO</li>
<li>
After this you should check the service detail page again and see the 86400s interval.
Even when you update your existing site to 1.4.0p11 or newer, you will have to apply the fix
manually to existing installations when your installation is affected.
Sites created with 1.4.0p11 or newer won't be affected.

Title: Sending service metrics to Graphite/InfluxDB can now be fine-tuned
Component: Core & setup
Level: 2
Class: New feature
Version: 1.5.0i1
Previously, there was a service rule to configure one of three levels of
information to be sent to Graphite/InfluxDB: Send nothing, send only value,
or send value/warn/crit/min/max.
Now the rule is more fine-grained, so one can choose for each part of the
metric if it should be sent or not. Furthermore, one can now send the unity
of measurement, too.

Title: Livestatus TCP: Can now be restricted to specific IP addresses
Component: Site Management
Level: 2
Class: New feature
Version: 1.5.0i1
When enabling livestatus access via TCP (via "omd config" or the WATO site management)
it is now possible to restrict the access to a set of client IP addresses.
The new option has been added to the global setting "Access to Livestatus via TCP" which
then sets the "omd config" option LIVESTATUS_TCP_ONLY_FROM.

Title: Major OMD config options can now be set via WATO global settings
Component: WATO
Level: 2
Class: New feature
Version: 1.5.0i1
The OMD configuration options that are used to configure basic aspects of
the Check_MK sites can now be configured via WATO. The settings are available
via "WATO > Global settings > Site Management".
These settings are activated during regular activate changes similar to the
other configuration settings.
It is also possible to set site specific option via the site specific global
settings.

Title: All recipents of an email are visible in notifications
Component: Notifications
Level: 2
Class: New feature
Version: 1.5.0i1
Notification multiplexing can now be used for HTML and ASCII emails.
By default it is enabled on new and existing Check_MK installations.
If notification multiplexing is enabled only one notification is generated
even if multiple recipients are going to be notified. Therefore, a
user can see and reply to all recipients of a notification.
Furthermore, the notification system will be more performant if graphs
are present in the notification the since only one notification is
generated. The notification multiplexing can be disabled in the section
Notification Method of a notification rule.
