"}" is missing at the end of logs when datadog extension on azure app service collects logs

[clgcn]

Hi all,

We are using datadog extension on azure app service to collect logs by agentless APM, it is missing "}" at the end of logs when the logs is deeply nested, the problem happen when json nested more than 3 layers.

The debug process as below:

1. I try to send logs to datadog by agentless serilog sink, the logs don't missing "}" at the end, the datadog give me a MessageTemplate event attributes, it doesn't missing "}" in this event attribute.
2. I try to write logs to Azure console, i check it in azure app service console , it doesn't missing "}" also.

Hi @clgcn - could you please clarify a couple of points:

• When you say "collect logs by agentless APM" you're using this configuration, correct?
• Could you confirm which logging library you're using? Nlog/Serilog/Log4Net/ILogger?
• Could you provide an example of the log message you're sending (e.g. how you're writing the log message in code), and how it looks in Datadog?

Thanks!

It is cause by the serilog, not datadog extension, thanks for you reply. https://github.com/serilog/serilog-sinks-file/issues/102
