Monitor high disk usage in your OCaml application

LogSnag makes it easy to track your OCaml application and monitor when it is experiencing high disk usage.

When building OCaml applications, we often end up dealing with persistent data in one way or another. This can be a simple JSON, CSV, or text file on disk, uploading files to cloud storage such as S3 or Google Cloud Storage, or even storing data in a database such as MongoDB or MySQL. In all of these cases, disk usage is a critical aspect of our OCaml application and can significantly affect the user experience.

Therefore, monitoring our OCaml application's disk usage is essential, whether in the local environment or somewhere in the cloud. This is critical as going over a certain threshold can cause our application to crash or become unavailable, resulting in a significant loss of revenue and user experience.

LogSnag is a powerful event tracking tool that works seamlessly with OCaml and makes it trivial to track any important event in our OCaml application in real time. For example, one common use case for LogSnag is tracking disk usage in real-time and setting up rules to notify our team and us when our disk usage has exceeded a certain threshold. This way, we can always be aware of the performance of our application and take immediate action if needed.

open Cohttp
open Cohttp_lwt_unix

let postData = ref "{\"project\":\"my-saas\",\"channel\":\"status\",\"event\":\"High Disk Usage\",\"description\":\"The disk usage is high.\",\"icon\":\"💾\",\"notify\":true}";;

let reqBody = 
  let uri = Uri.of_string "https://api.logsnag.com/v1/log" in
  let headers = Header.init ()
    |> fun h -> Header.add h "Content-Type" "application/json"
    |> fun h -> Header.add h "Authorization" "Bearer YOUR_API_TOKEN"
  in
  let body = Cohttp_lwt.Body.of_string !postData in

  Client.call ~headers ~body `POST uri >>= fun (_resp, body) ->
  body |> Cohttp_lwt.Body.to_string >|= fun body -> body

let () =
  let respBody = Lwt_main.run reqBody in
  print_endline (respBody)
