Chronicle-Engine-GUI

You first have to start a Chronicle Engine, for example, go to the chronicle engine project and run the main of :

Chronicle-Engine/src/test/java/net/openhft/chronicle/engine/StartEngineWithDummyData.java

Now from the Chronicle-Engine-GUI project, start the web based client management console, by starting a jetty application server:

mvn compile jetty:run

Then in your web-browser go to http://localhost:8080, if you are running using "StartEngineWithDummyData" ( see above ), you should be able to just use the defaults below :

click on "Login".

Network Latency

Network latency charts are only available when using queue replication, to measure network latency requires measuring the round trip time of replication events. Hence, network latency is only recorded for messages that are acknowledged. To see more about chronicle-queue message acknowledgement, see :

net.openhft.chronicle.queue.impl.WireStore.lastAcknowledgedIndexReplicated()

Queue-Replication is required to create data that can produce network traffic, you can run ( the following : )

Chronicle-Queue-Enterprise/src/test/java/net/openhft/chronicle/engine/StartEngineWithDummyData.java

This has to be run from the chronicle-queue-enterprise project ( Note: chronicle-queue-enterprise is a licensed project, if you wish to purchase a licence please contact [email protected])

Data Filtering

Below are some examples for range searching

a short hand for the above is :

if you want to find all values greater than say " 107.9", you can write this

if you want to also filter it to only show values greater than "107.9" and less than "110"

another way to write the same thing is :

we also support this inclusive "[" and exclusive "(" formats like below )

The time sample columns that feature a Long ( which is time in UTC milliseconds since epoch ), can be edited by clicking of the filter box, the following search dialog will appear :

once you click done you will see the UTC milliseconds range that this generates, for example

Data Ordering

If you click on the title this will order the data in your chart, click the title for second time will rerver the order of the data

further more if you click on another title and hold down the SIFT key, you get set up ordering on both titles at the same time, you can repeat this process across as many columns as you have
