kubernetes - Docker Exporter for Prometheus -


i have application different endpoints (rest services) runs in docker container in kubernetes pods.

these endpoints reachable like:

localhost:8080/myapp/status/health or

localhost:8080/myapp/status/version

i add of these endpoints (like health , version) prometheus metrics. need write exporter or exporters recommended use in senario?

it sounds looking key words , place start configure prometheus, running in kubernetes cluster, scrape data metrics end point.

i suggest add job_name 2 paths myapp/status/version , myapp/status/health prometheus configmap scrape_config section , make target ever app name called based on kube-dns assignment. actual domain name app_name appended namespace in: <app_name>.<k8s_namespace>.svc.cluster.local> localhost resolves on immediate system (i.e. laptop or pod itself) , tied 127.0.0.1 not routed within network kube-dns, pods & nodes technically have interface , there no way differentiate between them.

you can verify fqdn resolves getting k8s pod , issuing nslookup on combination. fqdn won't resolve outside of cluster meant routable within cluster -- unless build otherwise.

hth , luck configuration.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...
