* I've modified the snmp libraries so that the server and the community can be defined by the msg. Error will be thrown if you try to override what was defined in the node. Verified that the contents of msg is no longer clobbered. Signed-off-by: Bryan Malyn <bimalyn@us.ibm.com> * Replaced tabs with 4 spaces. Signed-off-by: Bryan Malyn <bimalyn@us.ibm.com> * fix extra spacing Signed-off-by: Bryan Malyn <bimalyn@us.ibm.com> * Standardise node.error to include msg so that errors can caught Signed-off-by: Bryan Malyn <bimalyn@us.ibm.com> * Update documentation for snmp nodes fixed documentation as noted, removed conflict and iff from documention remove node.warns if host or community are set in both the node config and msg Signed-off-by: Bryan Malyn <bimalyn@us.ibm.com> * FIX: Close net-snmp sessions Signed-off-by: Bryan Malyn <bimalyn@us.ibm.com> * Fix 2: The previous push did not cleanly address the problem. This commit uses a singleton aproach to create socket. It still needs to be tested to see if there is any issue to the never-close, but reuse socket model. My only concern is if a socket dies, do we need to do something to reestablish it? Signed-off-by: Bryan Malyn <bimalyn@us.ibm.com> |
