WebNMS SNMP API Go Edition distribution consists of the following,
SNMP API - a set of source codes developed using Golang to build SNMP management applications.
The product distribution also includes various example applications and executables (obtained when executing the build script, setEnv.sh or setEnv.bat that is present in the conf folder). It provides a hierarchy of golang packages for SNMP low-level, high-level, variables, etc, which helps in developing various non-UI applications.
Example applications included are asyncget, get, getnext, getbulk, inform, informd, set, trapd, trapv1, trapv2 & walk.
You can use them to query information from the SNMP agents on your network. All the applications that are used to query an agent have identical syntax. In general, all the command line tools gives help information when you type the following.
go run filename.go
For example, to get help information on the command snmpgetnext, type:
go run snmpgetnext.go
All the example applications can be executed by setting the proper Go environment variables (setenv.sh or setenv.bat) available in the conf directory.
Go SNMP API makes use of the Go lang's database/sql package (A package that provides a generic interface around SQL (or SQL-like) databases.) for database feature.
The above package has to be used in conjunction with a database driver, (i.e) you should download a database driver from the list of available drivers and import the same in your application. This is a prerequisite to use the Go SNMP API's database feature.
For the list of database drivers, see https://github.com/golang/go/wiki/SQLDrivers
After installing the driver, go through Database Support topic for further clarifications.
Golang guarantees compatibilty only at the source level. It does not guarentees compatibility for compiled packages between releases. So after every release (including minor release), Go sources has to be re-compiled to make it compatibile with the new release fo Go lang. See the link for more information regarding this.
As of now support for loading / unloading MIBs is not provided with this version. Manipulating OIDs should be done manually by hard-coding the OIDs to the application. However we are working on the MIBs support for our next release and it is very well in our future roadmap.
It is to be noted that the sources of the product are distributed under strict license. Users should report the bug to the support team - email@example.com.
If the reported issue is known to be a bug, it will be fixed by the snmp support team, and will be released in the next immediate minor release (whole sources in cumulative fashion as a zip). Based on the severity of the bug, issue will be fixed and minor release will happen. Customer specific patches will not be provided. So, if the fix is available in a latest release, the customer has to migrate to the latest version.
For example, the initial version of the product is 1.0 and as the new issues are reported and fixed, new minor releases will happen as 1.1, 1.2, 1.3 etc. Each minor releases may contain fix for a single issue or set of issues.
So, if the customer who is in version 1.1 and needs a fix that is present in the latest release say 1.6, he has to move to 1.6 because no customer specific patches will be provided over version 1.1. Or else if it is a new issue, it will be fixed and released as new minor release as version 1.7.
