This servlet makes the JMX health check results accessible via HTTP.
It is used to execute Sling Health Checks based on provided tags (if no tags are provided, all registered health checks will be executed). For the full list of provided health checks in AEM, go to https://localhost:4502/system/console/healthcheck.
Sample requests:
- https://host:port/system/health
- https://host:port/system/health?tags=shallow
- https://host:port/system/health?tags=shallow,security
- https://host:port/system/health?tags=shallow,security&combineTagsOr=false
Sample responses:
{
"results": [
{
"name": "Smoke Health Check",
"status": "OK",
"timeInMs": 1
}
]
}
{
"results": [
{
"name": "Bundle Health Check",
"status": "OK",
"timeMs": 0
},
{
"name": "Replication Queue Health Check",
"status": "OK",
"timeMs": 18
},
{
"name": "Sling Jobs Health Check",
"status": "OK",
"timeMs": 0
},
{
"name": "Startup Listener Check",
"status": "OK",
"timeMs": 1
}
]
}
A 200
status code will be returned if ALL health checks return the status OK. Otherwise a 503
is returned.
Note: It is assumed that all /system/*
paths are only accessible from a local network and not routed to the Internet.
This healthcheck can take an optional OSGi configuration file.
/apps/healthcheck/config/com.shinesolutions.healthcheck.hc.impl.ActiveBundleHealthCheck:
<?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:sling="https://sling.apache.org/jcr/sling/1.0" xmlns:jcr="https://www.jcp.org/jcr/1.0"
jcr:primaryType="sling:OsgiConfig"
bundles.ignored="[com.day.cq.dam.dam-webdav-support]"/>
With this configuration, the com.day.cq.dam.dam-webdav-support
bundle would be ignored in the ActiveBundleHealthCheck
.
Release artifacts are available for download via Maven Central at: https://repo1.maven.org/maven2/com/shinesolutions/aem-healthcheck-content/
This project uses Maven for building. Common commands:
From the root directory, run mvn -PautoInstallPackage clean install
to build the bundle and content package and install to a CQ instance.
From the bundle directory, run mvn -PautoInstallBundle clean install
to build just the bundle and install to a CQ instance.
- Navigate to the CRX Package Manager
- Upload the
aem-healthcheck-content-<version>.zip
package - Install the package
Create a release branch off the master
branch
git branch release/X.X
Prepare the release (use vX.X for the tag)
mvn release:prepare
Push the branch to the repository
git push origin
Checkout the newly created tag and build the project
git checkout tags/vX.X
mvn clean package
Attach the CRX package to the release on Github and merge back to master
.
The CRX host and port can be specified on the command line with:
mvn -Dcrx.host=otherhost -Dcrx.port=5502 <goals>
Besides the out-of-the-box tags, two new tags have been incorporated to the health check:
Tag | Health Checks | Description |
---|---|---|
shallow, devops | SmokeHealthCheck | This tag runs a simple Smoke health check that determines if an instance is running. |
deep |
|
This tag runs three different health checks.
