SYNOPSIS |
| 5 |
use AnyEvent::SNMP; |
| 6 |
use Net::SNMP; |
| 7 |
|
| 8 |
# just use Net::SNMP and AnyEvent as you like: |
| 9 |
|
| 10 |
# use a condvar to transfer results, this is |
| 11 |
# just an example, you can use a naked callback as well. |
| 12 |
my $cv = AnyEvent->condvar; |
| 13 |
|
| 14 |
# ... start non-blocking snmp request(s)... |
| 15 |
Net::SNMP->session (-hostname => "127.0.0.1", |
| 16 |
-community => "public", |
| 17 |
-nonblocking => 1) |
| 18 |
->get_request (-callback => sub { $cv->send (@_) }); |
| 19 |
|
| 20 |
# ... do something else until the result is required |
| 21 |
my @result = $cv->wait; |

DESCRIPTION |
| 24 |
This module implements an alternative "event dispatcher" for Net::SNMP, |
| 25 |
using AnyEvent as a backend. |
| 26 |
|
| 27 |
This integrates Net::SNMP into AnyEvent: You can make non-blocking |
| 28 |
Net::SNMP calls and as long as other parts of your program also use |
| 29 |
AnyEvent (or some event loop supported by AnyEvent), they will run in |
| 30 |
parallel. |
| 31 |
|
| 32 |
Also, the Net::SNMP scheduler is very inefficient with respect to both |
| 33 |
CPU and memory usage. Most AnyEvent backends (including the pure-perl |
| 34 |
backend) fare much better than the Net::SNMP dispatcher. |
| 35 |
|
| 36 |
A potential disadvantage is that replacing the dispatcher is not at all |
| 37 |
a documented thing to do, so future changes in Net::SNP might break this |
| 38 |
module (or the many similar ones). |
| 39 |
|
| 40 |
This module does not export anything and does not require you to do |
| 41 |
anything special apart from loading it *before doing any non-blocking |
| 42 |
requests with Net::SNMP*. It is recommended but not required to load |
| 43 |
this module before "Net::SNMP". |
