asgard tomcat application 404

[Tim Dunphy]

I'm trying to get Netflix Asgard tomcat app working. I'm using tomcat 9.
I'm using windows.

I can load up the tomcat management and other interfaces no problem.

But when I navigate to /asgard I get a 404 error:

HTTP Status 404 – Not Found
Type Status Report

Message /asgard/

Description The origin server did not find a current representation for
the target resource or is not willing to disclose that one exists.

Apache Tomcat/9.0.5

I have JAVA_HOME set to C:\Program Files\Java\jdk1.8.0_162

I placed the asgard.war file in the tomcat\webapps directory.

This is what I have in my catalina logs:

15-Feb-2018 15:59:30.048 INFO [main]

Skipping unneeded JARs during scanning can improve startup time and JSP
compilation time.

Yes. I did check the logs. It does not log anything when I deploy. But, it logs 
something when I undeploy.

Hi,



I just installed tomcat 8.5.23. I am having problems deploying web apps via 
manager. To reproduce:



1.   Login to tomcat manager



2.   Go to " WAR file to deploy"



3.   Pick a war file





Error message: FAIL - File upload failed, no file





Workaround: Copy war file to the tomcat webapps directory





I also tried using localhost:8080, same result. So, it's not some weird 
networking constraint.

You're running out of space in the JVM's Metaspace region (where class
metadata is stored), not system memory.  Metaspace is roughly
equivalent to PermGen from Java 7 and prior versions. The exception
means that you have more classes being loaded in the JVM than will fit
in your currently defined Metaspace. My first suggestion would be to
try increasing the size of Metaspace via the JVM argument
MaxMetaSpaceSize. I'd also suggest reading up on the exception in the
Oracle documentation for Java 8, here
https://docs.oracle.com/javase/8/docs/technotes/guides/troubleshoot/memleaks002.html
(search for Metaspace).

Hi All,

We are facing Out Of Memory issue in our Tomcat Server v8.5.20 as shown in the 
below logs.
Note: Though the error message says insufficient memory, we checked for the 
available physical memory on the server and there is sufficient amount of free 
memory available at the time of this Error.
The same set of applications are working fine without any issues on 
TC/7.0.35.B.RELEASE; JRE/1.7.0_17-b02
Hence any insights and recommendations to fix this issue will be very helpful. 
Thank you.

Hi Mark,

It sounds like you have a connection leak in your application. Enable abandoned 
connection logging to find out where the leaked connections are being created.

Verify your max connection is set high enough for the amount of traffic you see 
in your access logs that would be making a call to the DB.  Possible code is 
not properly closing DB connections.  Remove abandoned connections.
