示例1: snmpTranslate

// snmpTranslate resolves the given OID.
// The contents of the oid parameter will be replaced with the numeric oid value.
// If name is empty, the textual OID value is stored in it. If the textual OID cannot be translated, the numeric OID is stored instead.
// If mibPrefix is non-nil, the MIB in which the OID was found is stored, with a suffix of "::".

    if strings.ContainsAny(*oid, ":abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ") {
        out, err := execCmd("snmptranslate", "-m", "all", "-On", *oid)
        if err != nil {
            return Errorf(err, "translating %s", *oid)
