DataDog log into local log file

I am using DataDog 7.55.3 to write logs inside a local log file. The logs perfectly have been sent to our server that is installed, configured and provided by our Devops team... I tried to write the same logs into a local file log. However, no logs are written in local file.

According to the dataDog documentation and other resources, I create a folder with the name service.d inside the conf.d folder, I create conf.yaml file, I add following configs to the file

logs:
  - type: file
    path: "C:\\AppLogs.log"
    service: "service"
    source: "csharp"
    auto_multi_line_detection: true

I created the C:\AppLogs.log file with a full access to ddagent user...

Status page of the agent shows me the correct setup of file Log Agent:

service
Type: file
Path: C:\AppLogs.log
Service: service
Source: csharp
Status: OK
Inputs:
   C:\AppLogs.log
Bytes Read: 0
Pipeline Latency:
   Average Latency (ms): 0
   24h Average Latency (ms): 0
   Peak Latency (ms): 0
   24h Peak Latency (ms): 0

However, using LogFactory.LogInfo, the logs were collected into the server and are visible there, but they were not collected in file log.

Solution

  • The configuration you've posted is for having the agent read logs from the specified file, not write to it. Per the docs,

    To gather logs from your <APP_NAME> application stored in <PATH_LOG_FILE>/<LOG_FILE_NAME>.log create a <APP_NAME>.d/conf.yaml file at the root...

    Writing logs to that file would be dependent on configuring the logger in your application. This question and associated answers may help.
