Hello All,
Today I merged my changes into trunk from branch feature-new-threshold-
visitor.
This changes solve Bug 3146 and adds a new feature for Pollerd in-line
thresholding processing.
About the Bug 3146...
The old implementation couldn't maintain threshold's states across
configuration reloading. The new implementation is more intelligent
about that and can track:
a) If the configuration change is not related to currently triggered
thresholds, just simple keep state.
b) If the configuration changes is related to currently triggered
thresholds, send a special rearm (with NaN as current value, and a new
event parameter called reason with value: 'Configuration has been
changed'), in order to keep automations working fine. After that, new
configuration is merged to old one and new thresholds will use the new
configuration correctly.
c) If the configuration replaces currently triggered thresholds (for
example, you change a high threshold for a low threshold), the
procedure is similar to b).
About the new thresholding processor on Pollerd.
Now, you can add a special parameter called thresholding-enabled (like
you usually add it on collectd-configuration.xml) on a service
definition in poller-configuration.xml to enable thresholds
processing; for example:
<service name="ICMP" interval="300000" user-defined="false" status="on">
<parameter key="retry" value="2" />
<parameter key="timeout" value="3000" />
<parameter key="rrd-repository" value="/opt/opennms/share/rrd/
response" />
<parameter key="rrd-base-name" value="icmp" />
<parameter key="ds-name" value="icmp" />
<parameter key="thresholding-enabled" value="true" />
</service>
and then configure thresholds....
thresd-configuration.xml:
<package name="icmp-latency">
<filter>IPADDR != '0.0.0.0'</filter>
<include-range begin="1.1.1.1" end="254.254.254.254"/>
<service name="ICMP" interval="300000" user-defined="false"
status="on">
<parameter key="thresholding-group" value="icmp-latency"/>
</service>
</package>
thresholds.xml:
<group name="icmp-latency" rrdRepository="/opt/opennms/share/rrd/
response/">
<threshold type="high" ds-type="if" value="200.0" rearm="100.0"
trigger="1" ds-name="icmp"/>
</group>
Please test it and let me know if anyone found something wrong.
Regards,
Alejandro.
