# Where to find application logs

In the Wellcome installation, all the apps write their logs to our shared logging cluster. You can use these links to jump to a pre-filtered search for storage service logs:

* [in prod](https://logging.wellcomecollection.org/app/discover#/?_g=\(filters:!\(\),refreshInterval:\(pause:!t,value:0\),time:\(from:now-3h,to:now\)\)&_a=\(columns:!\(service_name,log\),filters:!\(\('$state':\(store:appState\),meta:\(alias:!n,disabled:!f,index:cb5ba262-ec15-46e3-a4c5-5668d65fe21f,key:ecs_cluster,negate:!f,params:\(query:storage-prod\),type:phrase\),query:\(match_phrase:\(ecs_cluster:storage-prod\)\)\)\),grid:\(columns:\(service_name:\(width:255.5\)\)\),index:cb5ba262-ec15-46e3-a4c5-5668d65fe21f,interval:auto,query:\(language:kuery,query:''\),sort:!\(!\('@timestamp',desc\)\)\))
* [in staging](https://logging.wellcomecollection.org/app/discover#/?_g=\(filters:!\(\),refreshInterval:\(pause:!t,value:0\),time:\(from:now-3h,to:now\)\)&_a=\(columns:!\(service_name,log\),filters:!\(\('$state':\(store:appState\),meta:\(alias:!n,disabled:!f,index:cb5ba262-ec15-46e3-a4c5-5668d65fe21f,key:ecs_cluster,negate:!f,params:\(query:storage-staging\),type:phrase\),query:\(match_phrase:\(ecs_cluster:storage-staging\)\)\)\),grid:\(columns:\(service_name:\(width:255.5\)\)\),index:cb5ba262-ec15-46e3-a4c5-5668d65fe21f,interval:auto,query:\(language:kuery,query:''\),sort:!\(!\('@timestamp',desc\)\)\))

{% hint style="info" %}
The indexer apps are *extremely* chatty (despite several attempts to make them quieter); the first step of searching the logs is usually to exclude those apps.
