We release a new plugin, check_hp_icf_sensors, for checking the sensors on a HP-ICF-CHASSIS MIB HP compliant device.

We go on exploring the wondoerful CISCO-ENTITY-FRU-CONTROL mib from Cisco. This week we offer the check_cisco_fru_module plugin, that allows to check modules status on CISCO-ENTITY-FRU-CONTROL-MIB compliant devices .

check_cisco_fru_module plugin allows us to check the status of all modules indicated through a list and compare with states indicated by the warning and critical arguments. check_cisco_fru_module has a mode test to check compatibility of a device too, is fully embedded Perl compatible (ePN) and can be downloaded from our website or through Nagios Exchange.

Some devices supporting this plugin are:

• ME 2400 Series Ethernet Access Switches
• ME 3400 Series Ethernet Access Switches
• Catalyst 2960 Series Switches
• Catalyst 2970 Series Switches
• Catalyst 3560 Series Switches
• Catalyst 3560-E Series Switches
• Catalyst 3750 Series Switches
• Catalyst 3750-E Series Switches
• Catalyst 3750 Series Integrated Wireless LAN Controllers
• Catalyst 6500 Series Switches
• XR 12000 Series Router
• ASA 5500 Series Adaptive Security Appliances
• PIX Firewall
• Nexus 7000 Series Switches
• ONS 15500 Series
• uBR7200 Series Universal Broadband Routers
• MWR 2900 Series Mobile Wireless Routers
• 7300 Series Routers
• 7600 Series Routers
• 10000 Series Routers
• 12000 Series Routers

Thanks so much to the needs of our customers and the great acceptance by the community of our plugins, and their continued feedback, we publish the  version 0.4b of our plugin to check memory consumptions en UNIXlike systems, check_unix_mem_usage.

We have extended the features of the plugin to make it more versatility and flexibility. These two new features offer the following qualities:

• Allows to choose whether you want to return in the performance data a metric with maximum system RAM.
• Allows to check the memory based on percentages but get the output in the desired units.

Thanks to these improvements we can make more interesting and comfortable our checks. On the one hand we can obtain performance data that allow us to draw graphs in which we will always have a clear reference to the top of RAM in the system. And on the other hand, we can plan checks on our systems without having to be aware of the existing RAM in each. On the above, for example, we would create a check that returning the memory values ​​in a given unit and establish warning or criticality states based on whether it exceeds the memory usage by 80% or 90%, respectively, allowing expand or reduce the memory available on the system without have to worry about adjusting the thresholds for the check.

The plugin is programmed in Perl and is compatible with Nagios 3.x (Embedded Perl). It comes with a README file in which is described in more detail the operation of this and its requirements. As always, the plugin can be downloaded from our website and more information is available through Nagios Exchange.

Results of reliability for our plugins

This week a new plugin is being released to the Nagios community. Following our current tendence, it can be used for monitoring CPD energy related issues.

This new plugin, formerly named check_pwnet_rpdu_load, allows checking the load level in each bank of a Powernet MIB compliant device (usually APC devices). A README file containing PDU background information is attached to the plugin.

The right usage of this plugin, Nagios 3.x (ePN) compatible, should report valuable data useful for taking decisions related to upgrading obsolete hardware, and thus, eficientless from a energy-saving point of view. As usually, we hope this plugin was as useful as possible to the Nagios community.

Siguiendo la política de publicación de contenidos para su uso por la comunidad, esta semana hemos liberado un nuevo plugin para Nagios bajo licencia GNU/GPL: check_ups_alarms permite comprobar qué alarmas activas existen en un SAI con soporte al RFC 1628 (UPS-MIB) lo que, usado conjuntamente con el plugin check_ups_mode permite realizar una monitorización del SAI, si no completa, sí relativamente avanzada.

Estamos orgullosos de ver el soporte que estos plugins están teniendo en la comunidad de usuarios de Nagios: en menos de 24 horas el nuevo plugin ha obtenido más de 100 hits  en la web de Nagios Exchange.

Invitamos a todos los usuarios de nuestros contenidos a que expreséis vuestra opinión, reportéis problemas o propongáis mejoras a través de nuestro blog o de la dirección de correo This e-mail address is being protected from spambots. You need JavaScript enabled to view it .

As we announced las week, this week we go on discovering CISCO-ENTITY-FRU-CONTROL from Cisco. Now is the turn to release check_cisco_fru_ps, that allows to check powers status on CISCO-ENTITY-FRU-CONTROL-MIB compliant devices (like Cisco MDS 9000 series).

check_cisco_fru_ps plugin allows us to check the status of all powers indicated through a list and compare with states indicated by the warning and critical arguments. check_cisco_fru_ps has a mode test to check compatibility of a device too, is fully embedded Perl compatible (ePN) and can be downloaded from our website or through Nagios Exchange.

We hope this new plugin will be useful. See you again.

After a low activity period (or rather, after highest activity period), we release this week a Nagios plugin very useful for those who use Cisco devices. check_cisco_envmon uses data stored in CISCO-ENVMON MIB for checking the hardware components status and the discrete levels of their functional values.

Plugin allows you checking the operational status of power supplies, fans, voltage and temperature levels managing these values:

• Normal: The component or checked value is healthy or in the operational value range.
• Warning: Component with degraded working state or values out of range but still not reaching critical values.
• Critical: Component working state is critical or the checked value level has raised critical values.
• Shutdown: Component status or value level is so degraded that the device will shutdown for auto protection.
• Not Present: Checked component is not present.
• Not Functioning: Checked component reports abnormal values, thus not functioning state is considered.

Relative to functional values, plugin returns voltage levels and temperature values as performance data.

We would like to thank Marcia Gross her help lighting our way in order to select what plugin to release this week (Marcia, we hope it has most useful for you).
