zipkin-scouter

Zipkin Scouter UDP storage and other zipkin-scouter integrations.

• Supported scouter collector version : v2.5+

Server integration

In order to integrate with zipkin-server, you need to use properties launcher to load your collector (or sender) alongside the zipkin-server process.

To integrate a module with a Zipkin server, you need to:

• add a module jar to the loader.path
• enable the profile associated with that module
• launch Zipkin with PropertiesLauncher

Each module will also have different minimum variables that need to be set.

Example integrating the Scouter Collector by Zipkin-Scouter-Storage

Here's an example of integrating the scouter Collector.

Step 1: Download zipkin-server jar

Download the latest released server as zipkin.jar:

cd /tmp
wget -O zipkin.jar 'https://search.maven.org/remote_content?g=io.zipkin.java&a=zipkin-server&v=2.12.9&c=exec'

Step 2: Download the latest zipkin-storage-scouter jar

Download the latest released Scouter module as zipkin-storage-scouter.jar:

cd /tmp
wget -O zipkin-storage-scouter.jar 'https://search.maven.org/remote_content?g=io.github.scouter-project&a=zipkin-autoconfigure-storage-scouter-udp&v=LATEST&c=module'

Step 3: Run the server with the "scouter" profile active

When you enable the "scouter" profile, you can configure scouter with short environment variables similar to other Zipkin integrations.

cd /tmp
SCOUTER_COLLECTOR_ADDR=127.0.0.1 \
SCOUTER_COLLECTOR_PORT=6100 \
SCOUTER_SERVICE_MAPS_OJB_TYPE= \
STORAGE_TYPE=scouter \
java -Dloader.path='zipkin-storage-scouter.jar,zipkin-storage-scouter.jar!lib' -Dspring.profiles.active=scouter -cp zipkin.jar org.springframework.boot.loader.PropertiesLauncher

• NOTE: Make sure the parameters are defined in the same line or use environment variables **

• Configures

  • STORAGE_TYPE=scouter : required. All others are optional.
  • SCOUTER_COLLECTOR_ADDR (default: 127.0.0.1) : Scouter collector IP
  • SCOUTER_COLLECTOR_PORT (default: 6100) : Scounter collector Port
  • SCOUTER_UDP_PACKET_MAX_BYTES (default: 60000) : should be smaller than OS UDP diagram size.
  • SCOUTER_TAG_MAP_TEXT1 : tag mapping to scouter xlog's predefined column text1 (default: spring.instance_id) (comma separated multi-tags supported.)
  • SCOUTER_TAG_MAP_TEXT2 : tag mapping to scouter xlog's predefined column text2 (comma separated multi-tags supported.)
  • SCOUTER_TAG_MAP_TEXT3 : tag mapping to scouter xlog's predefined column text3 (comma separated multi-tags supported.)
  • SCOUTER_TAG_MAP_TEXT4 : tag mapping to scouter xlog's predefined column text4 (comma separated multi-tags supported.)
  • SCOUTER_TAG_MAP_TEXT5 : tag mapping to scouter xlog's predefined column text5 (comma separated multi-tags supported.)
  • SCOUTER_TAG_MAP_LOGIN : tag mapping to scouter xlog's predefined dictionary encoded column login (just single first matching tag of comma separated tags is used for the column.)
  • SCOUTER_TAG_MAP_DESC : tag mapping to scouter xlog's predefined dictionary encoded column desc (just single first matching tag of comma separated tags is used for the column.)
  • SCOUTER_SERVICE_MAPS_OJB_TYPE : map a zipkin's local endpoint service name to a scouter objType (ex: system1:OrderSystem,system2:CustomerSystem ...). It use the same name of service name with preceding $z.
  • SCOUTER_DEBUG (default: false) : Debug option

Limitation

This currently only supports sending to a Scouter collector, not reading back spans from the service.
Spans can be shown in the Scouter's XLog view.
