SNMPA_NOTIFICATION_FILTER(3)

💖 snmpa_notification_filter — bestie edition 💖

okay so welcome to the manual page for snmpa_notification_filter, the Erlang module that lives under the snmp app. it's a behaviour module, which is just fancy talk for "here's a template, you fill in the blanks, queen."

✨ NAME ✨

snmpa_notification_filter — the behaviour module for SNMP agent notification filters. it's giving "you write the vibe, i'll handle the plumbing." 💅

---

🦋 DESCRIPTION 🦋

okay bestie, so this module defines the behaviour of the agent notification filters. if you wanna be a snmpa_notification_filter compliant module (iconic of you, honestly), you must export these functions:

• handle_notification/2

like, that's the whole vibe check. the semantics of 'em and their exact signatures get explained below, keep reading 🫶

so what's the purpose of notification filters, you ask? great question. it's to allow for modification and/or suppression of a notification. you can remix it or you can make it disappear, your call.

⚠️ heads up bestie: a misbehaving filter will be removed. no cap. act right or get evicted 😭

---

🌈 DATA TYPES 🌈

• notification() :: term(). — it's a term. that's it. that's the type.
• trap() :: term(). — also a term. we stay consistent 💜

---

🎀 CALLBACKS 🎀

handle_notification(Notif, Data)

Handle a notification to be sent. this is your moment, your main character energy ✨

the filter can do one of three things:

• accept the notification as is — return send
• modify the notification — return {send, NewNotif}
• suppress the notification — return dont_send

and Data? that's supplied at filter registration time, see snmpa:register_notification_filter/5. iykyk 💅

that's the whole page bestie, slay 💖
