Release Notes - GreenLight - Version 2.3.0
=20
New Features
=20
Maintenance
=20
=20
- GreenLight now updates a file named /opt/tomcat/logs/heartbeat.log ever=
y five minutes. The content is the time of the update in milliseconds since=
1970. This is aimed at providing external tools a method of monitoring the=
GL system. The last modified date of this file should never be older than =
five minutes, if Tomcat and the GL system are running.
=20
=20
Monitoring
=20
=20
- Clusters have been added as a type of network devices. A cluster in GL =
can contain 1-n custom defined servers. Clusters are detected during Domino=
Discovery, but can also be created and edited manually. Thus, clusters in =
GL may not necessarily identical to clusters in the Domino Directory.
=
=20
=20
=20
- Cluster/Server Availability Sensor: a new sensor has been added that is=
currently named "Domino Cluster Availability". It is the replacement for t=
he old sensor "Domino Availability", which will be discontinued with versio=
n 2.4.0. The new sensor is compatible with both servers as well as cluster =
nodes. In addition to the traditional values like availability index and la=
tency, the sensor will offer cluster specific values like e.g. "average ava=
ilability index" and "percent cluster members available".
=20
=20
=20
- Console Commands: An action is now available that allows executing of 1=
-n Domino console commands. It is recommended that this action is used in c=
ombination with its built in notification option, that allows sending of a =
mail whenever the action was triggered.
=20
=20
=20
- Domino Health: When double-clicking a server in the Domino Health Monit=
or, a new window will now open with specific Domino related information for=
the selected server. In this initial release the information has an overvi=
ew character, providing quick access to data about Domino server in general=
, its cluster and mailing status as well as an overview about its resource =
utilization. This area will be constantly improved over the next versions u=
ntil it extends to be a place for quickly gaining access to the more comple=
x aspects of Domino monitoring data. The goal is that this interface should=
not only provide the administrator with easier access to information, but =
also means to research possible causes or fix reoccurring issues (in its fi=
nal expansion stage).
=20
=20
=20
- Check 'mail.box' content: as part of above mentioned Domino Health (sub=
-category Mailing), this functionality allows the querying of server mail r=
outer boxes ('mail.box' files) for their content of dead, waiting or mails =
on hold. Domino statistics can sometimes be inaccurate regarding these stat=
istics, that is why this way of an on demand query has been added.
=20
=20
Live Monitor
=20
=20
- Domino Health Monitor Configuration: it is now possible to customize th=
e layout of the Domino health monitor data grid. Custom categories can be a=
dded as well as custom columns for either sensors or sensor categories. The=
se settings as well as reworked threshold preferences are stored user speci=
fic and will remain intact after log-off (sizes may vary depending on windo=
w arrangement).
(Notice: this new feature will start out with an initia=
l grid configuration very close to the former Domino Health grid, but the a=
vailability index will be taken from a Domino Cluster Availability sensor, =
not the Domino Statistics. This will have the effect that cluster nodes wil=
l be visible as well as Domino servers. Existing systems will have to creat=
e a new Domino Cluster Availability sensor to collect the data for this col=
umn) =20
=20
=20
- Full Screen Mode: when right-clicking on the Live Monitor window header=
, a context menu option "Full Screen" is now available. This will maximize =
the window beyond usual top and bottom bars. Alerts will still be shown on =
the top left in a non-intrusive way. The full screen mode can be exited by =
clicking the icon on the top right.
=20
=20
Improvements
=20
Maintenance
=20
=20
- A linux cron job is now checking the heartbeat file hourly if GL servic=
es are still online. If a service interruption is detected that could have =
been caused by a lockup, the virtual appliance is restarted.
=20
=20
Domino Discovery
=20
=20
- Clusters will now be detected during the discovery process.
=20
=20
General
=20
=20
- User Preferences: this area has been slightly reworked and notification=
settings now have the same look and feel as the rest of the preferences=20
=20
=20
- Sensor Creation Wizard: this wizard will now add a cluster availability=
sensor instead of the old availability sensor. In addition, a HTTP Access =
sensor will be activated on servers marked as HTTP servers. The disk statis=
tics sensor was rescheduled to run every 30 minutes and write to the databa=
se. An additional page will allow to make cluster assignments, and a cluste=
r availability sensor is automatically added to all the cluster nodes.

=20
=20
=20
- Mail Statistics Sensor: a number of charts have been added to this sens=
or's detail result display (e.g. mail size, delivery time, processing time)=
.
=20
=20
Monitoring
=20
=20
- Traffic Analysis Sensors: there is now an option to specify an attachme=
nt of configurable size when utilizing Domino replication or mail delivery =
sensors.
=20
=20
=20
- Domino Mail Delivery Sensor: mails can now be sent via SMTP gateways an=
d it is now also usable with echo-mail services that retain the original su=
bject.
=20
=20
=20
- Log Search Sensor: up to 100 log lines will now be retrieved by this se=
nsor. In sensor details, those will be displayed according to selected crit=
eria. An option has been added that the found lines can be sent per notific=
ation/eMail.
=20
=20
Charting
=20
=20
- Charting: it is now possible to right-click an axis in any chart to spe=
cify its maximum as maximum for all axis' in the chart. Previously that was=
only possible for column charts.
=20
=20
=20
- Line Charts: if an axis is used by more than one data series, its maxim=
um will be determined by visible series only.
=20
=20
Bug Fixes
=20
=20
- DB Access Sensor charting: a problem has been fixed that would prevent =
creating charts for this sensor. This was merely a display problem and all =
historical data collected while the bug existed should now be accessible ag=
ain.
=20
=20
=20
- Gray lights in network monitor: there has been a bug with sensor schedu=
ling that could result in loosing of a measurement cycle, which in turn wou=
ld result in a gray light, since a new measurement was expected but not per=
formed. If this problem occurs in an environment, simply opening the sensor=
configuration and saving the sensor again will solve it.
