first i'll introduce my working environment
net-snmp:net-snmp-5.4.2.1 src rpm
linux: fedora 11, i386
i have define a table in my mibfile, assume testTable
then i use mib2c -c mib2c.mfd.conf testTable to generate some code
and i load data in the function
int testTable_container_load(netsnmp_container * container)
which is in testTable_data_access.c
the way i load data is from a table in the database, however this table updated
very frequently
when it offer me to choose what way to work, this is my option
2) Set defaults now[DEFAULT] [2]
2) Yes, use my own structure [2]
[netsnmp_data_list *]
1) No, use generated[DEFAULT] [1]
1) no, no initialization needed [1]
1) All values will be stored as defined by the MIB[DEFAULT] [1]
2) container-cached [2]
2) Yes. My data is SEMI-TRANSIENT [2 ]
1) generate example code [DEFAULT] [1]
1) No, all columns always exist for every row[DEFAULT] [1]
1) do not generate makefile/AgentX code[DEFAULT] [1]
the option is in left, and the right is my answer
and i set cache_timeout 60 s
i have an external program periodically send snmpwalk request to get all the
data in snmp
i met question like that
assume the first quest can trigger loading data function
however it can dump all the data in the container after it send part data and
then load_data again
however this data will not be the last data load, so i get some uncorrect
record.
whether there's other implemention that we i do snmpwalk. it only load data
once, after i finished it
it can dump, then i do snmpwalk again, it load data again.
and i tried another
2) Set defaults now[DEFAULT] [2]
2) Yes, use my own structure [2]
[netsnmp_data_list *]
1) No, use generated[DEFAULT] [1]
1) no, no initialization needed [1]
1) All values will be stored as defined by the MIB[DEFAULT] [1]
1) container : [DEFAULT] [1]
2) Yes. My data is SEMI-TRANSIENT [2 ]
1) generate example code [DEFAULT] [1]
1) No, all columns always exist for every row[DEFAULT] [1]
1) do not generate makefile/AgentX code[DEFAULT] [1]
this time i choose container mode, however the program didn't call
testTable_container_load
ps i use
./testTable -f -Dverbose -M
so that i can see the calling infomation
