MONGOC_APM_SE...BEAT_FAILED_CB(3)

🦋 MONGOC_APM_SE...BEAT_FAILED_CB(3) 🦋

okay bestie, so this is a libmongoc man page and it's lowkey a niche one but we're gonna slay it ✨. It's all about the callback that fires when the driver's little "hello" check-up to a server goes wrong. Very "checking in on your friend and they left you on read" energy tbh 💀.

---

✨ SYNOPSIS ✨

typedef void (*mongoc_apm_server_heartbeat_failed_cb_t) (
   const mongoc_apm_server_heartbeat_failed_t *event);

void
mongoc_apm_set_server_heartbeat_failed_cb (mongoc_apm_callbacks_t *callbacks,
                                           mongoc_apm_server_heartbeat_failed_cb_t cb);

So what's the vibe? You get an event notification whenever the driver fails to send a "hello" command to check the status of a server 🫶. That's it. That's the whole personality. It's giving "the ping didn't land" 😭.

💡 note: the "hello" in quotes is literally part of the command name — keep the quotes, they're iconic.

🌸 PARAMETERS 🌸

• callbacks — a mongoc_apm_callbacks_t. You know her, you love her, she's the callbacks struct. 💅
• cb — a function to call with a mongoc_apm_server_heartbeat_failed_t whenever the driver fails to send a "hello" command to check the status of a server. Like, the driver tried to check on the server and it didn't work, so it hands you the whole event and you do your thing 🎀.
