Hello everyone,
I have generated a C code with mib2c tool, than implemented
it according to my need. Everything is working fine .I have assigned values
with system calls. These system call calling a shell script and getting
output from there. When I am using SNMPGET or WALK it gives correct values
. I am running these scripts with infinite for( ; ; ) loop to get the data.
Bt when I am trying to get these data with SNMPWALK after 10-15 times it
is returning me all the values " 0 " .What may be the reason behind it? I
want that it should return a correct value continuously, What methods or
changes I can do ??
Please help me ..
Below are my functions..
Thanks in advance.
int
handle_cpuPercentUsage(netsnmp_mib_handler*handler,netsnmp_handler_registrat
ion *reginfo,
netsnmp_agent_request_info *reqinfo,netsnmp_request_info
*requests) {
for(;;)
{
int *dat=(int *)temp(); /// temp function for getting
value
switch(reqinfo->mode)
{
case MODE_GET:
snmp_set_var_typed_value(requests->requestvb,
ASN_INTEGER,
(u_char
*)&dat,sizeof(dat));
break;
default:
snmp_log(LOG_ERR, "unknown mode (%d) in
handle_cpuPercentUsage\n",
reqinfo->mode );
return SNMP_ERR_GENERR;
}
return SNMP_ERR_NOERROR;
sleep(1);
}
}
int temp()
{
int temp=0;
FILE *pipe = NULL;
/* cpu.sh is a script which returns value between 0-100 */
pipe=popen("/home/jatin/net-snmp-5.7.2.rc1/agent/mibgroup/cpu.sh","r");
if(pipe != NULL)
{
if( fscanf(pipe,"%d",&temp) != -1)
{
return temp;
}
}
}
