Custom java agent doesn't work with v5

[krismarc]

@ramonskie, a simple project jar with applicationinsights-agent.jar added on the root archive level

The same works with old ruby based java buildpack

Please note adding APPLICATIONINSIGHTS_CONNECTION_STRING is essential, otherwise it doesn't start the agent and error doesn't occur

I believe this might be some command evaluation problem that leads to running the jar in a wrong way and java's help is getting printed out.

Maybe this option needs quotes as the command line does not like * and | symbols outside quotes.

-Dhttp.nonProxyHosts=localhost|*.companyapps-np.com|*.companyapps.com|*.gwpnet.com|*.appcloud.company.com|*.ac.company.com|*.ac-np.company.com|*.company.com

->

-Dhttp.nonProxyHosts="localhost|*.companyapps-np.com|*.companyapps.com|*.gwpnet.com|*.appcloud.company.com|*.ac.company.com|*.ac-np.company.com|*.company.com"

[krismarc]

That was my first suspect. However, if there's no javaagent then it works with those proxy settings (without any modifications).
This worked without quotation with Ruby version.

[krismarc]

Actually, as far as I remember, in other buildpack (not sure about java one), extra quotation used to became part of pipe-separated value, which was causing leading and trailing one to be invalid..

[krismarc]

Maybe this option needs quotes as the command line does not like * and | symbols outside quotes.

-Dhttp.nonProxyHosts=localhost|*.companyapps-np.com|*.companyapps.com|*.gwpnet.com|*.appcloud.company.com|*.ac.company.com|*.ac-np.company.com|*.company.com

->

-Dhttp.nonProxyHosts="localhost|*.companyapps-np.com|*.companyapps.com|*.gwpnet.com|*.appcloud.company.com|*.ac.company.com|*.ac-np.company.com|*.company.com"

hmm, it worked, wondering why it fails only in combination with extra javaagent only
..I still need to check what happens to leading and trailing values of noproxy

[stokpop]

Ah I see something else: there is a ; in the connection string... looking at the buildpack code that gets probably translated into:

java -javaagent:applicationinsights-agent-3.7.8.jar -Dapplicationinsights.connection.string=InstrumentationKey=ABCD-1234;IngestionEndpoint=https://westeurope-1.in.applicationinsights.azure.com/ --version

This will break the command at ; and not show the version info, but java usage instead.

With quotes:

java -javaagent:applicationinsights-agent-3.7.8.jar -Dapplicationinsights.connection.string="InstrumentationKey=ABCD-1234;IngestionEndpoint=https://westeurope-1.in.applicationinsights.azure.com/" --version

it correctly shows version info via the --version.

Also with an extra backspace (instead of additional quotes) it works from the commandline: \;

java -javaagent:applicationinsights-agent-3.7.8.jar -Dapplicationinsights.connection.string=InstrumentationKey=ABCD-1234\;IngestionEndpoint=https://westeurope-1.in.applicationinsights.azure.com/ --version

So maybe the connection string needs to be quoted from

java-buildpack/src/java/frameworks/azure_application_insights_agent.go

Line 171 in 9ce86e2

opts = append(opts, fmt.Sprintf("-Dapplicationinsights.connection.string=%s", credentials.ConnectionString))

[krismarc]

sorry! update to my previous proxy statements, I've been testing against old buildpack!

for ruby version it works no matter if quotation is used or not
for go version it doesn't work neither the value is quoted or not

Ah I see something else: there is a ; in the connection string... looking at the buildpack code that gets probably translated into:

java -javaagent:applicationinsights-agent-3.7.8.jar -Dapplicationinsights.connection.string=InstrumentationKey=ABCD-1234;IngestionEndpoint=https://westeurope-1.in.applicationinsights.azure.com/ --version

This will break the command at ; and not show the version info, but java usage instead.

With quotes:

java -javaagent:applicationinsights-agent-3.7.8.jar -Dapplicationinsights.connection.string="InstrumentationKey=ABCD-1234;IngestionEndpoint=https://westeurope-1.in.applicationinsights.azure.com/" --version

it correctly shows version info via the --version.

So maybe the connection string needs to be quoted from

java-buildpack/src/java/frameworks/azure_application_insights_agent.go

Line 171 in 9ce86e2

opts = append(opts, fmt.Sprintf("-Dapplicationinsights.connection.string=%s", credentials.ConnectionString))

..on my way to test.

[krismarc]

@stokpop, that's the right catch! I've tested escaped semicolon and it worked.

  APPLICATIONINSIGHTS_CONNECTION_STRING: 'InstrumentationKey=<guid>\;IngestionEndpoint=https://westeurope-1.in.applicationinsights.azure.com/'

..unfortunately, due to environment restrictions, I can't build the buildpack on my own to test changes in Line 171 in 9ce86e2. I assume, someone has to come up with a PR 😄

btw, has anyone ever considered allowing env vars like JAVA_OPTS to be provided as a list, so buildpack would convert it back to raw string? this would be a nice feature. Maintaining lists in devops tools/scripts would be a way easier to handle.

The weird things is: I tried to create a failing integration test with (this is inside the golang integration test code) "APPLICATIONINSIGHTS_CONNECTION_STRING": "InstrumentationKey=12345678-1234-1234-1234-123456789abc;IngestionEndpoint=https://eastus-1.in.applicationinsights.azure.com/" for the Azure application insights, but it does not fail even though I see no escaping being applied:

USER         PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND

and checking the generated JAVA_OPTS:

vcap@6c8355f29121:~/profile.d$ export DEPS_DIR=/home/vcap/deps/
vcap@6c8355f29121:~/profile.d$ bash -x 0_00_java_opts.sh
...

Does it behave different with other setup? This is on linux with the 5.0.2 buildpack in docker cloudfoundry/cflinuxfs4:latest.

Not sure if I gave it a try with double quotes - I'll try tomorrow. First attempt was done without quotes at all and the other one with single quotes and escaped semi-colon. Still, ruby version worked without quotes at all.

[krismarc]

so luck with double quoted value, only single quoted with escaped semi-colon worked so far
APPLICATIONINSIGHTS_CONNECTION_STRING: 'InstrumentationKey=<guid>\;IngestionEndpoint=https://westeurope-1.in.applicationinsights.azure.com/'

[krismarc]

it's pretty weird, I just noticed that cf push differently treats different envs, could be that it's unrelated and it's just how cf push log behaves

APPLICATIONINSIGHTS_CONNECTION_STRING never inherits any quotation marks
and in case of LOG4J_FORMAT_MSG_NO_LOOKUPS it turns single quotes into double quotes..

manifest:
    APPLICATIONINSIGHTS_CONNECTION_STRING: InstrumentationKey=guid-guid;IngestionEndpoint=https://westeurope-1.in.applicationinsights.azure.com/
    LOG4J_FORMAT_MSG_NO_LOOKUPS: true
cf push output:
