Monitorizare servere prin SNMP

one more thing..... /var/log/cron n-ar trebui sa-mi arate ca ruleaza ceva din 5 in 5 min?

daca rulez comanda din crontab manual merge...pe localhost afiseaza graficele cum trebuie. iata in schimb ce apare in cacti.log la executie pt aceeasi masina, dar in loc de localhost am dat adresa placii de retea (log partial)

1. verifica daca cron ruleaza si daca ai adaugat linia corect in crontab
2. cand rulezi comanda din crontab, o rulezi sub userul cacti ?
3. nu ai ceva filtre in firewall care sa nu iti permita conectarea pe portul 161 UDP la la localhost ? (dinspre localhost spre ip-ul placii de retea)

am probleme in a adauga SNMP - Interface Statistics....mai exact:

Data Query [SNMP - Interface Statistics]  
This data query returned 0 rows, perhaps there was a problem executing this data query. You can run this data query in debug mode to get more information.

Data Query Debug Information zice asa:
+ Running data query [1].
+ Found type = '3' [snmp query].
+ Found data query XML file at '/var/www/html/cacti/resource/snmp_queries/interface.xml'
+ XML file parsed ok.
+ Executing SNMP walk for list of indexes @ '.1.3.6.1.2.1.2.2.1.1'
+ No SNMP data returned
+ Found data query XML file at '/var/www/html/cacti/resource/snmp_queries/interface.xml'
+ Found data query XML file at '/var/www/html/cacti/resource/snmp_queries/interface.xml'

toate acestea petrecandu-se pentru localhost, pentru eth0. ceva sugestii?
