check_snmp_load.pl with -T netsl uses wrong oid #66

Open hboetes opened 5 years ago

hboetes commented 5 years ago

Using the latest version from git I get this:

# ./check_snmp_load.pl -v -H habocp1 -C public -2 -T netsl -w 5,5,4 -c 7,7,5
Alarm in 5 seconds
SNMP v2c login
Checking linux load
ERROR: Description table : The requested table is empty or does not exist.

And that's because the wrong oid is requested.

 00:00:00.000000 5a:61:54:8f:4c:42 > ac:1f:6b:28:03:c0, ethertype IPv4 (0x0800), length 87: 10.10.8.17.33869 > 10.10.10.230.161:  GetBulk(30)  N=0 M=25 .1.3.6.1.2.1.25.3.3.1.1

If I'd request the right oid I do get an answer:

# snmpwalk -v2c -c public habocp1 .1.3.6.1.4.1.2021.10.1.3.3                
iso.3.6.1.4.1.2021.10.1.3.3 = STRING: "0.28"

Reading the code:

# Generic with host-ressource-mib                                                                                              
my $base_proc = "1.3.6.1.2.1.25.3.3.1";      # oid for all proc info                                                           
my $proc_id   = "1.3.6.1.2.1.25.3.3.1.1";    # list of processors (product ID)                                                 
my $proc_load = "1.3.6.1.2.1.25.3.3.1.2";    # %time the proc was not idle over last minute                                    

# Linux load                                                                                                                   

my $linload_table = "1.3.6.1.4.1.2021.10.1";      # net-snmp load table                                                        
my $linload_name  = "1.3.6.1.4.1.2021.10.1.2";    # text 'Load-1','Load-5', 'Load-15'                                          
my $linload_load  = "1.3.6.1.4.1.2021.10.1.3";    # effective load table

I don't have access to such a test system, can you send a PR please?

Hello @dnsmichi, thanks for your reply. What do you mean with a PR? This is on an ubuntu 18.04 host.

Hello @dnsmichi,

Ah, now I get it. If I would know the solution I would have made a PR. Alas, the code is beyond me.
