AJP connector stats in WildFly

[pdhaigh]

Hi,

Is it possible to obtain the same runtime statistics for the AJP connector in WildFly 8 that it was in JBossAS 7?

For instance:

AS7:

[standalone@localhost:9990 /] ./subsystem=web/connector=ajp:read-resource(include-runtime=true)

{

    "outcome" => "success",

    "result" => {

        "bytesReceived" => "19563",

        "bytesSent" => "149216136",

        "enable-lookups" => false,

        "enabled" => true,

       "errorCount" => "586",

        "executor" => undefined,

        "max-connections" => undefined,

        "max-post-size" => 2097152,

        "max-save-post-size" => 4096,

        "maxTime" => "1527",

        "name" => "ajp",

       "processingTime" => "122014",

        "protocol" => "AJP/1.3",

        "proxy-name" => undefined,

        "proxy-port" => undefined,

        "redirect-port" => 8433,

       "requestCount" => "4176",

        "scheme" => "http",

        "secure" => false,

        "socket-binding" => "ajp",

        "ssl" => undefined,

        "virtual-server" => undefined

    }

}

WildFly 8:

[standalone@localhost:9990 /] ./subsystem=undertow/server=default-server/ajp-listener=ajp:read-resource(recursive=true, include-runtime=true)

{

    "outcome" => "success",

    "result" => {

        "allow-encoded-slash" => false,

        "always-set-keep-alive" => true,

        "buffer-pipelined-data" => true,

        "buffer-pool" => "default",

        "decode-url" => true,

        "enabled" => true,

        "max-cookies" => 200,

        "max-header-size" => 51200,

        "max-headers" => 200,

        "max-parameters" => 1000,

        "max-post-size" => 10485760L,

        "redirect-socket" => "https",

        "scheme" => undefined,

        "socket-binding" => "ajp",

        "url-charset" => "UTF-8",

        "worker" => "default"

    }

}

AFAIK it is not possible out of box, since these calculations have performance implications and if they are not used, they should not be calculated. Mod_cluster adds some logic do the the counts for the sake of letting know the load-balancer how much load is on the server (wildfly/mod_cluster/undertow/src/main/java/org/wildfly/mod_cluster/undertow/metric at master · wildfly/wildfly · GitHub).

What do you need the information for?

[pdhaigh]

I was looking to view these stats to compare between JBoss AS 7 and WildFly 8.. the reason being is that as you can see in the stats pasted above from JBoss AS 7, I am seeing high percentage error coun. I wanted to compare to determine if it was worth investigating why, or just move to WildFly 8 if the problem seemed resolved.

So my next step is to raise a question as to why there are high error counts on JBoss AS 7: High error counts on AJP connector (JBoss AS 7.1)

Many thanks,

In my case, the mentioned parameters are used to report/monitor the health/statistics of the application. If they are not available out of the box, then how we could implement those?

There is a feature request issue opened for this: [WFLY-3274] Expose connector metric values such as requestCount , maxTime, bytesReceived, etc - JBoss Issue Tracker (you might want to add as watcher)

Well, as I linked before you could always add these implementations wildfly/mod_cluster/undertow/src/main/java/org/wildfly/mod_cluster/undertow/metric at master · wildfly/wildfly · GitHub yourself...
