I am using CapeDwarf JBoss AS7 to host classic GAE+GWT application. On server side, I am logging directly to java.util.Logger framework.
The application works fine, the logs print nice to the console and files.
However, all my logs, together with some http request logs, are also stored in the datastore. Yes, every log line becomes one datastore entity. This should not surprise me, because it is stated in the docs (http://www.jboss.org/capedwarf/docs) and it is needed in order to display logs in gae-like admin console of CapeDwarf.
I was looking for a way to disable this useful but expensive feature. I cannot find any docs that would tell me what to do if I do not need/want my logs in the datastore (e.g. right now 98.3% of my datastore are __org.jboss.capedwarf.LogRequest__ and __org.jboss.capedwarf.LogLine__ entities!). Does anyone happen to know how to do it?

I want to check latencies of RPC every day about CakePHP Application each endpoints running in GKE cluster. I found it is possible using php google client or zipkin server by reading documents , but I don't know how easy to introduce to our app though both seem tough for me.
In addition, I'm concerned about GKE cluster configuration has StackDriver Trace option though our cluster it sets disabled.Can we trace span if it sets enable?
Could you give some advices?
I succeeded to send gcp's trace api in php client via REST. It can see trace set by php client parameters , but my endpoint for trace api has stopped though I don't know why.Maybe ,it is not still supported well because the document have many ambiguous expression so, I realized watching server response by BigQuery with fluentd and DataStudio and it seem best solution because auto span can be set by table name with yyyymmdd and we can watch arbitrary metrics with custom query or calculation field.
I like that I can use the Logs API (described here: https://cloud.google.com/appengine/docs/java/logs/) to programatically access and display app & request logs as I see fit--it's great.
Now that I'm using Managed VMs on AppEngine you can see on the Admin Console Logs Viewer that there are a ton of additional logs--including in my case a custom log which I found I could include in the viewer (decribed here: https://cloud.google.com/appengine/docs/managed-vms/custom-runtimes#logging).
My question is: Is there any way I can use the Logs API (or other pipelines already built?) to access these logs? My Managed VM module includes several components which could produce logs that I want to view:
App logs -- I can get these! No problem here.
Custom log files created by background processes I kick off in _ah/start (like "my_custom_1.log" in the screenshot)
STDERR & STDOUT from my background processes
Relevant Managed VM logs (e.g. for when an instance was restarted due to bad health... other system events like normal restarts?)
Basically I want "the total picture" at the instance level. Anyone tried to tame Managed VMs in this way with success? I'm not looking forward to rolling my own solution. And I wouldn't even know where to start on the problem of capturing STDERR and STDOUT. Any help appreciated.
There is a difference between App Engine logging and Google Cloud logging. Some of the Managed VM logs go to both, but much of it only goes to cloud logging.
Until recently there was not an API to read Cloud logs, only to write them. However, there is a new v2 beta API: https://cloud.google.com/logging/docs/api/introduction_v2
To do things at an instance level, entries in Cloud logging should have metadata set to denote which VM they came from. Both of these values seem to vary on logs from my VMs:
compute.googleapis.com/resource_name
compute.googleapis.com/resource_id
I'm building some reporting tool. Ideally I want to avoid going through web server logs myself and use (some of) the power of Piwik.
The stuff I get from the visitor log would be a good start, this is at http://example.com/piwik/index.php?module=CoreHome&action=index&idSite=1&period=day&date=yesterday#/module=Live&action=getVisitorLog&idSite=1&period=day&date=yesterday
Unfortunately I can't find a getVisitorLog action in the HTTP API docs at
http://developer.piwik.org/api-reference/reporting-api#Actions (and it's also not an undocumented feature, method=Actions.getVisitorLog gives me
The method 'getVisitorLog' does not exist or is not available in the module '\Piwik\Plugins\Actions\API'.
Is there another way to get to this? Or should I write a plugin for Piwik?
Apparently it is possible through the Live plugin API:
http://developer.piwik.org/api-reference/reporting-api#Live
This works as desired:
http://example.com/piwik/index.php?module=API&method=Live.getLastVisitsDetails&format=JSON&idSite=1&period=day&date=2015-07-21&expanded=1&token_auth=XXXXX&filter_limit=100
I'm trying to migrate an a web app from Google Appengine to a dedicated server and I've got stuck to the logging issue. Basically I would like to organise the logs per request/context(like on GAE) so that I can easily review the errors/trace on each request. The most advanced logging library I could find is the glog package but still I can't figure it out how to log per request/context.
Each request gives you a http.Request-object to work with.
If you're using sessions, then you'll have a sessions.Session-object to work with.
You will want to use those objects to help log per request/context, as they identify the request / session.
UPDATE: Please, if anyone can help: Google is waiting for inputs and examples of this problem on their bug tracking tool. If you have reproducible steps for this issue, please share them on: https://code.google.com/p/googleappengine/issues/detail?id=10937
I'm trying to fetch data from the StackExchange API using a Google App Engine backend. As you may know, some of StackExchange's APIs are site-specific, requiring developers to run queries against every site the user is registered in.
So, here's my backend code for fetching timeline data from these sites. The feed_info_site variable holds the StackExchange site name (such as 'security', 'serverfault', etc.).
data = json.loads(urllib.urlopen("%sme/timeline?%s" %
(self.API_BASE_URL, urllib.urlencode({"pagesize": 100,
"fromdate": se_since_timestamp, "filter": "!9WWBR
(nmw", "site": feed_info_site, "access_token":
decrypt(self.API_ACCESS_TOKEN_SECRET, self.access_token), "key":
self.API_APP_KEY}))).read())
for item in data['items']:
... # code for parsing timeline items
When running this query on all sites except Stack Overflow, everything works OK. What's weird is, when the feed_info_site variable is set to 'stackoverflow', I get the following error from Google App Engine:
HTTPException: Invalid and/or missing SSL certificate for URL:
https://api.stackexchange.com/2.2/me/timeline?
filter=%219WWBR%28nmw&access_token=
<ACCESS_TOKEN_REMOVED>&fromdate=1&pagesize=100&key=
<API_KEY_REMOVED>&site=stackoverflow
Of course, if I run the same query in Safari, I get the JSON results I'm expecting from the API. So the problem really lies in Google's URLfetch service. I found several topics here on Stack Overflow related to similar HTTPS/SSL exceptions, but no accepted answer solved my problems. I tried removing cacerts.txt files. I also tried making the call with validate_certificate=False, with no success.
I think the problem is not strictly related to HTTPS/SSL. If so, how would you explain that changing a single API parameter would make the request to fail?
Wait for the next update to the app engine (scheduled one soon) then update.
Replace browserid.org/verify with another service (verifier.loogin.persona.org/verify is a good service hosted by Mozilla what could be used)
Make sure cacerts.txt doesnt exist (looks like you have sorted but just in-case :-) )
Attempt again
Good luck!

I was facing the same error, google has updated the app engine now, error resolved, please check the updated docs.
