| <h2>We're Incubating!</h2> |
| <p class="relNotesText">The Traffic Control project has been accepted into the Apache Incubator, and is |
| thus now Apache Traffic Control (incubating). Beyond simply moving the website, |
| this necessitated a number of changes, including changing the license header on each file. |
| </p> |
| |
| <p class="relNotesText">The 1.8.0-incubating release is Apache Traffic Control's |
| first release under the Apache incubator. This release contains numerous bug |
| fixes in addition to the following: |
| </p> |
| |
| <h3>Traffic Router</h3> |
| <p class="relNotesText">Recommendations based on load testing of HTTPS support: </p> |
| |
| <p class="relNotesText">It is generally recommended to use the G1 garbage collector for JVM |
| applications running on multi core machines. In addition to using the G1 |
| garbage collector, the InitiatingHeapOccupancyPercent was lowered to run |
| garbage collection more frequently. This improved overall throughput for |
| Traffic Router and reduced 'Stop the World' garbage collection. </p> |
| <p class="relNotesText">The following example of /opt/tomcat/bin/setenv.sh that |
| has been tested on a multi core server running under HTTPS load test requests. |
| Note that setting the min and max heap settings in setenv.sh will override init |
| scripts in /etc/init.d/tomcat.</p> |
| |
| <pre><code> |
| #! /bin/sh |
| export CATALINA_OPTS="$CATALINA_OPTS -server" |
| export CATALINA_OPTS="$CATALINA_OPTS -Xms2g -Xmx2g" |
| export CATALINA_OPTS="$CATALINA_OPTS -XX:+UseG1GC" |
| export CATALINA_OPTS="$CATALINA_OPTS -XX:+UnlockExperimentalVMOptions" |
| export CATALINA_OPTS="$CATALINA_OPTS -XX:InitiatingHeapOccupancyPercent=30" |
| </code></pre> |
| |
| <h3>Traffic Stats</h3> |
| <ul> |
| <li>As of 1.8 Traffic Stats now requires InfluxDB 1.0 or greater. For support of InfluxDb version < 1.0 please use Traffic Stats 1.7.</li> |
| <li>Traffic Stats now uses its config file to determine which influxdb urls to use. This allows a user to run a single instance of influxdb, an enterprise clustered solution, or a HA solution using influxdb-relay (https://github.com/influxdata/influxdb-relay).</li> |
| |
| <li>It is recommended to use the traffic_stats.cfg file provided by the TS 1.8 RPM. This version of the config file contains the new InfluxUrls array and there were some unnecessary variables that were removed.</li> |
| </ul> |
