Re: string as index of a table
Hi Niels, But using a query like: snmpwalk $host .1..\"ABCDE\" is not working also. Below are the test results : snmpget $host .1..10."66.67.68.69.70.71.72.73.74.75" .1.."BCDEFGHIJK" = INTEGER: 0 snmpget $host .1..10.\"ABCDEFGHIJ\" .1..10."ABCDEFGHIJ": Unknown Object Identifier (Index out of range: "ABCDEFGHIJ") snmpget $host .1..10.'ABCDEFGHIJ' .1..10.ABCDEFGHIJ: Unknown Object Identifier (Index out of range: ABCDEFGHIJ ) Could you please help in resolving this?

Re: string as index of a table
Hi, I've seen this technique used by a major telecom vendor, so it's certainly technically doable. They included DateAndTime and a name string as part of the index on trap varbinds. I would advise you to find a different way, though, just for the reasons you mention. It's not human-readable at all, and while our NMS system calculates the corect OID values by a script, it took time to develop and it was hell to work with when integration testing. Maybe you could keep the strings as row values in another table, and use a shared numeric index for the two tables, to map them together?

string as index of a table
Hello, Could you please if it is advisable to use a string eg. name of item as a table index? The table is yet to be defined, need defined and added to a MIB file. The table will contain info of different items and our requirement is if we can get the info of a particular item by doing snmpget query passing the item name string as index. I have tested it, it is feasible, but while giving the OID in snmpget, we needed to give the item name string index by dot separated ascii values of each character in the name. eg. .1..5."65.66.67.68.69" where the item name is "ABCDE". But from usage perspective it is not looking good that we need to manually calculate the ascii values of the characters in the item name and provide them in the snmpget query. Is there any other way of doing this so that we can directly give the item name and not the ascii values? Some thing like: .1..5."ABCD" or .1..5."A.B.C.D" thanks and regards S Sarath-- Comprehensive Server Monitoring with Site24x7. Monitor 10 servers for $9/Month.
