## Quick Start
|
|
|
|
### Basic SNMP Operations
|
|
|
|
# Simple SNMP GET operation
|
|
{:ok, {type, value}} = SnmpKit.SnmpLib.Manager.get("192.168.1.1", [1, 3, 6, 1, 2, 1, 1, 1, 0])
|
|
|
|
# SNMP GETBULK for efficient bulk retrieval
|
|
{:ok, results} = SnmpKit.SnmpLib.Manager.get_bulk("192.168.1.1", [1, 3, 6, 1, 2, 1, 2, 2],
|
|
max_repetitions: 20)
|
|
|
|
# SNMP SET operation
|
|
{:ok, :success} = SnmpKit.SnmpLib.Manager.set("192.168.1.1", [1, 3, 6, 1, 2, 1, 1, 5, 0],
|
|
{:string, "New System Name"})
|
|
|
|
### High-Performance Connection Pooling
|
|
|
|
# Start a connection pool for network monitoring
|
|
{:ok, _pid} = SnmpKit.SnmpLib.Pool.start_pool(:network_monitor,
|
|
strategy: :device_affinity,
|
|
size: 20,
|
|
max_overflow: 10
|
|
)
|
|
|
|
# Use pooled connections for improved performance
|
|
SnmpKit.SnmpLib.Pool.with_connection(:network_monitor, "192.168.1.1", fn conn ->
|
|
SnmpKit.SnmpLib.Manager.get_multi(conn.socket, "192.168.1.1", oids, conn.opts)
|
|
end)
|
|
|
|
### Intelligent Error Handling
|
|
|
|
# Retry operations with exponential backoff
|
|
result = SnmpKit.SnmpLib.ErrorHandler.with_retry(fn ->
|
|
SnmpKit.SnmpLib.Manager.get("unreliable.device.local", [1, 3, 6, 1, 2, 1, 1, 1, 0])
|
|
end, max_attempts: 5, base_delay: 2000)
|
|
|
|
# Circuit breaker for problematic devices
|
|
{:ok, breaker} = SnmpKit.SnmpLib.ErrorHandler.start_circuit_breaker("192.168.1.1")
|
|
result = SnmpKit.SnmpLib.ErrorHandler.call_through_breaker(breaker, fn ->
|
|
SnmpKit.SnmpLib.Manager.get_bulk("192.168.1.1", [1, 3, 6, 1, 2, 1, 2, 2])
|
|
end)
|
|
|
|
### Performance Monitoring and Analytics
|
|
|
|
# Start monitoring system
|
|
{:ok, _pid} = SnmpKit.SnmpLib.Monitor.start_link()

|
|
|
# Record operation metrics
|
|
SnmpKit.SnmpLib.Monitor.record_operation(%{

|
|
operation: :get,
|
|
duration: 245,
|
|
result: :success
|
|

|
|
|
# Get device statistics and health scores
|
|
stats = SnmpKit.SnmpLib.Monitor.get_device_stats("192.168.1.1")
|
|
IO.puts("Device health score: " <> to_string(stats.health_score))
|
|
|
|
# Set up automated alerting
|
|
SnmpKit.SnmpLib.Monitor.set_alert_threshold("192.168.1.1", :response_time, 5000)

timeout = SnmpKit.SnmpLib.Config.get(:snmp, :default_timeout, 5000)
|
|
pool_size = SnmpKit.SnmpLib.Config.get(:pool, :default_size, 10)

|
|
|
# Hot-reload configuration
|
|
:ok = SnmpKit.SnmpLib.Config.reload()

|
|
### Real-Time Dashboard and Monitoring
|
|
|
|
# Start dashboard with Prometheus integration

|
|
|
# Warm cache for predictable access patterns
|
|
SnmpKit.SnmpLib.Cache.warm_cache("device_1", :auto, strategy: :predictive)
|
|
|
|
