Hi Dave,
Thanks again for your support.
First of all I would like to tell you that my Perl version is: "v5.12.2
built for i386-linux-thread-multi".
Secondly I would like to describe the way I would like to bind the values
to my columns: netSnmpPrvOWD and netSnmpPrvATR:
I'm using a program that will write every 1 second in 2 files de values
that I need: eth0_delay.out and eth0_datarate.out.In those files it is
only one row that contains a string[15] that represent the measured
values from my interface. If I understood right, the agent will read those
files every time it has a get request, so practically I got rid of using a
thread. I wanted to use the static values just for
testing but unfortunately I didn't succeed, so that's why I would like to ask
you if is not to
much to help with that piece of code for netSnmpPrvTable_load() that
will bind my values (from files or static).
This is what I have tried to do:
##################################################################################
int
netSnmpPrvTable_load(netsnmp_cache * cache, void *vmagic)
{
netsnmp_tdata *table = (netsnmp_tdata *) vmagic;
netsnmp_tdata_row *row;
FILE *fp;
char buf[STRMAX];
struct netSnmpPrvTable_entry *entry;
printf("Reading file: eth0_delay.out\n");
fp = fopen("/tmp/eth0_delay", "r");
long netSnmpPrvIndex=1;
netsnmp_tdata_row *this;
printf("loading cache: %d\n" ,(int) &cache);
// while (fgets(buf, STRMAX, fp)) {
/*
* Unpick 'buf' to extract the index values...
*/
//////////////////////////////////////////////// Trying to bind static
values/////////
row->data = entry;
strcpy(entry->netSnmpPrvOWD,"1234");
entry->netSnmpPrvOWD_len=4;
strcpy(entry->netSnmpPrvOWD,"4321");
entry->netSnmpPrvOWD_len=4;
entry->netSnmpPrvIndex = 1;
netsnmp_tdata_row_add_index(row, ASN_INTEGER,
&(entry->netSnmpPrvIndex),
sizeof(entry->netSnmpPrvIndex));
netsnmp_tdata_add_row(table,
row);
//////////////////////////////////////////////////////////////////////////////////////
this = netSnmpPrvTable_createEntry(table, netSnmpPrvIndex);
/*
* ... and then populate 'this' with the column values
*/
// }
fclose(fp);
return;
}
############################################################################
when I start the subagent it looks like:
cache created: -1078654040
table refistered: -1078654036
NET-SNMP version 5.5 AgentX subagent connected
netSnmpPrvTable_subagent is up and running.
And then for the request: snmpget -v2c -c public localhost
.1.3.6.1.4.1.8072.9999.9999.1.2.1.2.1
the subagent displays: handling request: 160 and I get the response:
NET-SNMP-MIB2::netSnmpPrvOWD.1 = No Such Instance currently exists at
this OID
So again please help me to fix this.
