snmp_standard_mib(3)

💖 snmp_standard_mib — the STANDARD-MIB glow-up 💖

okay bestie, welcome to snmp_standard_mib(3), which is the Erlang module definition page for snmp_standard_mib 🎀 This is the one that keeps STANDARD-MIB and SNMPv2-MIB fed and happy, so buckle up.

✨ NAME ✨

snmp_standard_mib — the instrumentation functions for STANDARD-MIB and SNMPv2-MIB 🫶

---

🌸 DESCRIPTION 🌸

So like, this module snmp_standard_mib is the one doing the actual work — it implements the instrumentation functions for the STANDARD-MIB and SNMPv2-MIB, plus it's got the functions you use to configure the database. It's giving backstage crew at the MIB concert, fr fr. 💅

The configuration files get explained in the SNMP User's Manual — go read that if you want the full lore. ✨

👑 FUNCTIONS 👑

💫 configure(ConfDir) -> snmp:void() when ConfDir :: string()

This one gets called from the supervisor at system start-up. Very main character entrance, ngl. 🦋

Here's what it does, no gatekeeping:

• It inserts all the data from the configuration files into the database, and it destroys all old rows with StorageType volatile. Bye bestie 💀
• The rows it creates from the configuration file get StorageType nonVolatile — they're the ones staying.
• All snmp counters get set to zero. Fresh start, periodt.
• If there's an error in the configuration file, it gets reported using the function config_err/2 of the error report module, and then the function fails with the reason configuration_error. 😭

And ConfDir is a string that points to the directory where the configuration files live.

The configuration file it reads is: standard.conf.

💫 inc(Name, N) -> snmp:void() when Name :: atom(), N :: integer()

Increments a variable in the MIB with N — or with one, if N isn't specified. Small bump, big energy. ✨

💫 reconfigure(ConfDir) -> snmp:void() when ConfDir :: string()

Okay so this is configure's bolder sibling. 💅

• It inserts all the data from the configuration files into the database and destroys all old data, including the rows with StorageType nonVolatile. Yes, even those. Everything. Gone. 🫶
• The rows created from the configuration file will have StorageType nonVolatile.
• So basically, after you call this, the data in the SNMP-STANDARD-MIB and SNMPv2-MIB is from the configuration files. Clean slate, iconic behaviour.
• All snmp counters are set to zero.
• If an error is found in the configuration file, it's reported using the function config_err/2 of the error report module, and the function fails with the reason configuration_error.

And ConfDir, again, is a string pointing to the directory where the configuration files are found.

The configuration file read is: standard.conf.

💫 reset() -> snmp:void()

Resets all snmp counters to 0. That's it, that's the whole vibe check. 💖

💫 sys_up_time() -> Time when Time :: integer()

Gets the system up time in hundredth of a second. So like, tiny little slices of seconds — very precise of it. ⭐

heads up bestie: if the config file is messy, things don't just get sad, they literally fail with configuration_error and report through config_err/2. Keep standard.conf clean and we're golden 💜
