Pandora: Pandora Migration 6.0 to 7.0
1 Quick guide to migrating functions from Pandora FMS 6.0 to version 7.0
The focus of this quickguide is to tell you about the most important functions that have changed for the new release, as well as some of the actions you'll have to perform.
1.1 Network Maps
On Pandora FMS 7.0 NG the classic network maps have gone, and the Network Console has been improved. This means that all the prior network maps will be lost during migration, and you'll have to replace them by creating Network Consoles. In the new version you can see the different monitored interfaces from the Network Console, and associate them directly from there, making configuration easier as you can perform it directly on the map, without having to configure anything on the modules.
These connections must be configured via the network recon itself, but in case it doesn't execute, and you have to perform the connections manually, it can be done like this:
1.2 L2 Recon tasks
The standard Recon task (Network sweep) has been augmented with an option that was previously carried out by the SNMP Script, SNMP L2 Recon. This script will still function on version 7.0 NG after migration the embedded changes within Network Sweep mode that improve interface links between different network devices won't be incorporated in the SNMP L2 Recon script.
1.3 Renaming agents
This is a feature that clients have been demanding. In previous versions this change had to be performed on the console and the config file, making it a tedious task depending on the number of elements to be modified.
To solve this problem we have developed a new element known as Alias. From now on, two elements will coexist under the umbrella of a single agent label, the name and the alias.
On installations migrated from version 6 to version 7, this element remains the same:
Now, if you want to modify the visible name of an agent it will be enough to modify the Alias to see it displayed with this name on all displays:
The Agent name calculation on version 7.0NG created from now on will be created via a set of random sentences. This means that if there are two machines with the same hostname, there will be two agents with different Agent names but the same Alias on the Pandora FMS console.
If you wish to avoid this situation (e.g., if the agent software vmware plugin is installed in the Pandora environment on VMs and you want the data from both sources on the same logic agent) you can indicate the agent to behave as in previous versions and create an agent with the same Alias and agent Name. To do this, introduce the following parameters in the agent software's config file:
#agent_name 5fa9bdc9ad26a4d0e87d0f0d15ed786c3bd487441b2d5e8d7c42b90e8389797d #agent_name_cmd __rand__
Done like this, the agent will be created with the same name as always, and with the information it receives from both sources. You can still change the alias from the console if necessary and the information will appear as normal.
In case you update the agent or satellite servers the config files in use need to be saved, if not, and they are deleted, a new randomly-labeled agent will be generated and the stored history data will be lost, unless the two parameters above are entered in the same configuration.
1.4 New Pandora FMS agents
The default information the agents report has altered in this new version of Pandora FMS v. 7.0 NG, being now unified and consolidated.
These are the new modules that will generate reports:
Linux agent
Windows agent
Agents will maintain the same configuration in their modules after migration, provided it is not a new agent. Modules included in version 7.0 won't be added automatically.
Here's the configuration you have to add in the above case:
Linux agent
# Could change depending on linux distro and vmstat command version
module_begin
module_name CPU Load
module_type generic_data
module_interval 1
module_exec vmstat 1 2 | tail -1 | awk '{ print $13 }'
module_max 100
module_min 0
module_description User CPU Usage (%)
module_min_warning 70
module_max_warning 90
module_min_critical 91
module_max_critical 100
module_unit %
module_group System
module_end
# Could change depending on linux distro and vmstat command version

module_description Too much IOwait means IO bottleneck and performance problems. Check also LoadAVG.
module_group System

1.5 Update Manager / Rolling Release
Pandora FMS 0.7 NG enables users to make database changes in OUM packets that are subsequently distributed. Go to the Update Manager Online or Offline section, depending whether there is a connection or not.
1.5.1 Update Manager Online
Go to this section via Update Manager > Update Manager Online.
If you're installing a new version a message like this will appear:
Click “Update to the latest version”:
When the update is accepted, the following packet is downloaded and applied. If the packet also contains the database changes the following message will appear before the changes are applied in order to facilitate database backup and ensure that, in case of error when applying new scripts, the previous database status is recoverable.
When MR is applied the database changes are made and once the process has finalized the updated and applied version should appear:
1.5.2 Update Manager Offline
Go to Update Manager > Update Manager Online.
Upload the packet in the option that appears:
Once the packet is applied, the following message appears:
If the upload implies database changes, these are applied and the following message appears:
To find out which version you're using, there is a new field at the console footer that tells you which MR or database version it is, and whether the changes have been applied:
1.6 New alert templates
New templates have been added for this release:
They come installed on Pandora FMS 7.0 NG, but migrations from previous versions won't be applied, to respect previous configurations.
1.7 Interface monitoring nomenclature
Monitoring nomenclature has been modified, and modules are now monikered to more easily order their information via their interface label.
The following nomenclature was used in previous versions:
This is the new format:
In order to fully take advantage of Pandora FMS 7.0 NG's new features, like Enterprise maps, interface graphs, etc. the module's names need to be modified with the following SQL queries:
UPDATE tagente_modulo SET nombre = CONCAT(REPLACE(nombre, 'ifOperStatus_', ''), '_ifOperStatus') WHERE nombre LIKE('ifOperStatus_%');
UPDATE tagente_modulo SET nombre = CONCAT(REPLACE(nombre, 'ifInOctets_', ''), '_ifInOctets') WHERE nombre LIKE('ifInOctets_%');
UPDATE tagente_modulo SET nombre = CONCAT(REPLACE(nombre, 'ifOutOctets_', ''), '_ifOutOctets') WHERE nombre LIKE('ifOutOctets_%');
To configure satellite server modules manually in the config file the modules must be renamed in the satellite config file (NOTE: if remote configuration is activated, they must be updated on the server, and the .md5 must be modified, or deleted from the server, renamed on the satellite and resent).
Execute from the server in case remote config is deactivated:
sed -i -e 's/ifOperStatus_\(.*\)/\1_ifOperStatus/' /etc/pandora/conf/*.conf sed -i -e 's/ifInOctets_\(.*\)/\1_ifInOctets/' /etc/pandora/conf/*.conf sed -i -e 's/ifOutOctets_\(.*\)/\1_ifOutOctets/' /etc/pandora/conf/*.conf sed -i -e 's/ifOperStatus_\(.*\)/\1_ifOperStatus/' /var/spool/pandora/data_in/conf/*.conf sed -i -e 's/ifInOctets_\(.*\)/\1_ifInOctets/' /var/spool/pandora/data_in/conf/*.conf sed -i -e 's/ifOutOctets_\(.*\)/\1_ifOutOctets/' /var/spool/pandora/data_in/conf/*.conf
After application these changes must be applied on the satellite server config. To do this, modify the .md5 file on each agent by inputting a random value on each of them.
echo 1 >/var/spool/pandora/data_in/md5/*.md5
