+corresponding to metric or event publishers to the messaging system.
+
+The address in the I<Transport> block concatenated with the name given in the

+
+=item B<Format> B<Command>|B<JSON>|B<Graphite>
+
+Selects the format in which messages are sent to the intermediary. If set to

+identical to the syntax used by the I<Exec> and I<UnixSock plugins>. In this

There are two types of blocks that can be contained in the
C<E<lt>PluginE<nbsp> snmp_agentE<gt>> block: B<Data> and B<Table>:
-=head3 The B<Data> block
+=head3 B<Data> block
The B<Data> block defines a list OIDs that are to be handled. This block can
define scalar or table OIDs. If B<Data> block is defined inside of B<Table>
=over 4
-=item B<Instance> I<true|false>
+=item B<IndexKey> block
+
+B<IndexKey> block contains all data needed for proper index build of snmp table.
+In case more than
+one table B<Data> block has B<IndexKey> block present then multiple key index is
+built. If B<Data> block defines scalar data type B<IndexKey> has no effect and can
+be omitted.
+
+=over 8
+
+=item B<Source> I<String>
-When B<Instance> is set to B<true>, the value for requested OID is copied from
-plugin instance field of corresponding collectd value. If B<Data> block defines
-scalar data type B<Instance> has no effect and can be omitted.
+B<Source> can be set to one of the following values: "Hostname", "Plugin",
+"PluginInstance", "Type", "TypeInstance". This value indicates which field of
+corresponding collectd metric is taken as a SNMP table index.
+
+=item B<Regex> I<String>
+
+B<Regex> option can also be used to parse strings or numbers out of
+specific field. For example: type-instance field which is "vcpu1-cpu2" can be
+parsed into two numeric fields CPU = 2 and VCPU = 1 and can be later used
+as a table index.
+
+=item B<Group> I<Number>
+
+B<Group> number can be specified in case groups are used in regex.
+
+=back
=item B<Plugin> I<String>
=back
+=item B<PersistentNotification> B<true>|B<false>
+Override default configuration to only send notifications when there is a change
+in the lifecycle state of a domain. When set to true notifications will be sent
+for every read cycle. Default is false. Does not affect the stats being
+dispatched.

+ * stdendian.h
+ *
+ * This header defines the following endian macros as defined here:
+ * http://austingroupbugs.net/view.php?id=162
+ *
+ * BYTE_ORDER this macro shall have a value equal to one
+ * of the *_ENDIAN macros in this header.
+ * LITTLE_ENDIAN if BYTE_ORDER == LITTLE_ENDIAN, the host
+ * byte order is from least significant to
+ * most significant.
+ * BIG_ENDIAN if BYTE_ORDER == BIG_ENDIAN, the host byte
+ * order is from most significant to least
+ * significant.
+ *
+ * The following are defined as macros:
+ *
+ * uint16_t bswap16(uint16_t x);
+ * uint32_t bswap32(uint32_t x);
+ * uint64_t bswap64(uint64_t x);
+
+ * uint16_t htobe16(uint16_t x);
+ * uint16_t htole16(uint16_t x);
+ * uint16_t be16toh(uint16_t x);
+ * uint16_t le16toh(uint16_t x);
+ *
+ * uint32_t htobe32(uint32_t x);
+ * uint32_t htole32(uint32_t x);
+ * uint32_t be32toh(uint32_t x);
+ * uint32_t le32toh(uint32_t x);
+ *
+ * uint64_t htobe64(uint64_t x);
+ * uint64_t htole64(uint64_t x);
+ * uint64_t be64toh(uint64_t x);
+ * uint64_t le64toh(uint64_t x);
+ *
+ * The header defines the following macro for OpenCL compatibility
+ *
+ https://www.khronos.org/registry/cl/sdk/2.0/docs/man/xhtml/preprocessorDirectives.html
+ *
+ * __ENDIAN_LITTLE__ if BYTE_ORDER == LITTLE_ENDIAN then this
+ * macro is present for OpenCL compatibility
+ *
+ * The implementation provides a uniform interface to endian macros using only
+ * system headers on recent Linux, Darwin, FreeBSD, Solaris and Windows
+ systems.
+ *
+ * This approach is intended to avoid the need for preflight configure
+ scripts.
+ * An alternative approach would be to test compiler CPU architecture marcros.
+ *
+ * This header has had *limited* testing on recent C11/C++11 compilers and is
+ * based on the austin bug tracker interface, manpages, and headers present in
+ * Linux, FreeBSD, Windows, Solaris and Darwin.
+ *
+ * The header uses __builtin_bswapXX intrinsic with GCC/Clang (__GNUC__) on
+ * platforms that do not provide bswap16, bswap32, bswap64 (Darwin)
+ *
+ * Public Domain.

- * stdendian.h
- *
- * This header defines the following endian macros as defined here:
- * http://austingroupbugs.net/view.php?id=162
- *
- * BYTE_ORDER this macro shall have a value equal to one
- * of the *_ENDIAN macros in this header.
- * LITTLE_ENDIAN if BYTE_ORDER == LITTLE_ENDIAN, the host
- * byte order is from least significant to
- * most significant.
- * BIG_ENDIAN if BYTE_ORDER == BIG_ENDIAN, the host byte
- * order is from most significant to least
- * significant.
- *
- * The following are defined as macros:
- *
- * uint16_t bswap16(uint16_t x);
- * uint32_t bswap32(uint32_t x);
- * uint64_t bswap64(uint64_t x);
-
- * uint16_t htobe16(uint16_t x);
- * uint16_t htole16(uint16_t x);
- * uint16_t be16toh(uint16_t x);
- * uint16_t le16toh(uint16_t x);
- *
- * uint32_t htobe32(uint32_t x);
- * uint32_t htole32(uint32_t x);
- * uint32_t be32toh(uint32_t x);
- * uint32_t le32toh(uint32_t x);
- *
- * uint64_t htobe64(uint64_t x);
- * uint64_t htole64(uint64_t x);
- * uint64_t be64toh(uint64_t x);
- * uint64_t le64toh(uint64_t x);
- *
- * The header defines the following macro for OpenCL compatibility
- *
- https://www.khronos.org/registry/cl/sdk/2.0/docs/man/xhtml/preprocessorDirectives.html
- *
- * __ENDIAN_LITTLE__ if BYTE_ORDER == LITTLE_ENDIAN then this
- * macro is present for OpenCL compatibility
- *
- * The implementation provides a uniform interface to endian macros using only
- * system headers on recent Linux, Darwin, FreeBSD, Solaris and Windows
- systems.
- *
- * This approach is intended to avoid the need for preflight configure
- scripts.
- * An alternative approach would be to test compiler CPU architecture marcros.
- *
- * This header has had *limited* testing on recent C11/C++11 compilers and is
- * based on the austin bug tracker interface, manpages, and headers present in
- * Linux, FreeBSD, Windows, Solaris and Darwin.
- *
- * The header uses __builtin_bswapXX intrinsic with GCC/Clang (__GNUC__) on
- * platforms that do not provide bswap16, bswap32, bswap64 (Darwin)
- *
- * Public Domain.
