Playing with the code to see if I can make batch import

If you have a linux machine, the code works but doesn't add a graph but gives an idea what is happening

It should also be sourced: then call the subroutine from cmd line

Code:


#!/bin/bash

lists(){
        type=$1
        shift
        extra=$*
        php5 cli/add_graphs.php  $type $extra
}

plingit(){
        sed "s/\(.*\)/'\1' /"
}

hosts(){
        {
                lists --list-hosts
        } | grep [0-9]
}

hostids(){
        eval harray=( $(hosts|plingit) )
        for h in $(seq 0 $(( ${#harray[@]}-1)) );do
                eval hline=( ${harray[$h]} )
                eval hostid=${hline[0]}
                echo $hostid
        done
}

cleanup(){
        grep -v "Known" | grep [a-z,A-Z]
}

snmpvalues(){
        hostid=$1
        snmpfield=$2
        {
                lists --list-snmp-values --host-id=$hostid --snmp-field=$snmpfield
        } | cleanup
}

snmpfields(){
        hostid=$1
        {
                lists --list-snmp-fields --host-id=$hostid
        } | cleanup
}

doit(){
        for hostid in $(hostids);do
                for snmpfield in $(snmpfields $hostid);do
                        for snmpvalue in $(snmpvalues $hostid $snmpfield);do
                                echo "'$hostid';$snmpfield;$snmpvalue"
                        done
                done
        done
}

{
cat  <<EOF
Please source the script ...

For referance:

php5 cli/add_graphs.php \
--host-id=$hostid --graph-template-id=2 \
--graph-title="$hostid $snmpvalue" \
--graph-type=ds \
--snmp-query-id=1 --snmp-query-type-id=13 \
--snmp-field=$snmpfield --snmp-value=$snmpvalue

EOF
}


Please note that there are cleanup routines to get rid of blank lines and verbose comments in the output of add_graphs
- it would be nice if the add_graphs just put out the result and left verbose for a parameter
Makes bash parsing a lot easier if they did ...

This will be edited every now and again.

It seems that cacti has a lib/api_automation_tools.php that is included by the cli tools:
Code:
function api_tree_item_save($id, $tree_id, $type, $parent_tree_item_id, $title, $local_graph_id, $rra_id,
function get_host_templates() {
function get_hosts_by_description() {
function getHosts() {
function get_addresses() {
function getSNMPFields($hostId) {
function getSNMPValues($hostId, $field) {
function getSNMPQueries() {
function getSNMPQueryTypes($snmpQueryId) {
function displayQueryTypes($types) {
function getGraphTemplates() {
function display_host_templates($host_templates) {
function display_communities() {
function displaySNMPFields($fields, $hostId) {
function displaySNMPValues($values, $hostId, $field) {
function displaySNMPQueries($queries) {
function displayGraphTemplates($templates) {
function displayHosts($hosts) {


And some of the cli tools
Code:
add_device.php  copy_user.php                    poller_reindex_hosts.php
add_graphs.php    rebuild_poller_cache.php
add_perms.php   poller_graphs_reapply_names.php
add_tree.php    poller_output_empty.php


So is this enough?

Well, for my own cisco case, I need something like:

if (description_on($device, $interface) add_graph($device,$interface,$graph_template,$graph_txt)

Can we get there?
add_graphs can list-hosts via library so the key host $id is available by searching for the $device so that is left to the reader
$interface is also possible to get ifDesc
--host-id=$id --snmp-field=ifDesc --list-snmp-values
$graph_template is also availale
--list-graph-templates
$graph_txt is really a function of host name graph template ifDescr and ifAlias: needs work...

But the problem now is to find out via cacti's library, which interfaces for a host have a description.
It is possible to scan one's backups but...
So at some stage I will try and define what the api library could give access to: but I have to thonk sorry think first or else one wasts one's time.

Input welcome
(solution being worked on is http://forums.cacti.net/viewtopic.php?t=23193)


Please note that
--host-id=$id --snmp-field=ifAlias --list-snmp-values
doesn't show duplicated descriptions, just unique list.
