This section discusses some of the best practices for IT360.
For Performance Tuning aspects of IT360 Best Practices, please refer to the link: https://manageengineit360.wiki.zoho.com/IT360-Best-Practices-Guide.html
It is suggested that you strictly follow the hardware and software / OS requirements as outlined in the following link and thereby avoid product hanging / crashing issues.

All editions of IT360 can be installed in a VM environment and it needs to meet the System Requirements as per point 1 above. You may use VMs when you wanto reduce the number of physical server / boxes.
To ensure a smooth user and functional and implementation experience, we recommend you to follow and comply with the prerequisites outlined in our help document.

These mostly relate to
It is a good practice to keep a constant watch on the network / bandwidth speed with respect to the following scenarios:
If you plan to use the Failover option offered by IT360, it is recommended to use MSSQL as the backend database.
If you are an MSP, offering services using IT360, it is suggested to understand your client's environment and discuss the same with our support team so as to assist you with handling any typical situations, very specific to this client.
This happens typically in a multi-customer, MSP environment that uses a shared IT360 Probe. When you have two machines of same IP addresses from a single customer or different customers, one of the machines will have to be monitored through a different Probe.
You may use the NAT support offered in IT360 when communication / reachability between the Central Server and Probes [or with the devices] needs to happen over the internet. This feature is particulary useful for MSPs
Whenever you want to report a problem to our support team, it is a good practice to send us a screen shot and also the log files. Also, ensure to tell us the scenario / environment / situation clearly, when you face a problem. You may send us the complete Support Information File that is automatically generated by the click of a hyper link [the Support -- Create Support File link on the top right corner of IT360 UI]. You may email us the same. Where the log files and screen shots are huge, of the order of several MBs, we suggest you to ftp / upload them to one of our public servers, the details of which are available in the above mentioned Support page.
It is a good practice to take periodic backup of the databases and the configuration files. For details, please refer to the following link:

It is advised not to overload a Probe or a Central Server beyond its recommended scalability.
It is recommended to install / use a new probe when it crosses the following limits:
Number of network interfaces [devices monitoring] = 8000
Number of server / applications instances = 500
Number of router interfaces for netflow monitoring = 200
It is recommended to use a new Central Server, when the load on it crosses the following limits [sum of all the probes put-together]:
Number of network interfaces [devices monitoring] = 40,000
Number of server / applications instances = 2000
Number of router interfaces for netflow monitoring = 1000
Number of Probes per Central Server = 50
Please note thar the load on the server also depends on the Polling interval, etc., and hence it is advisable to take the help of our Support team on arriving at the final numbers.
When your requirement is to ensure an uninterupted monitoring and managment of your network using IT360, it is good to use the Failover feature.
IT360 has several modules - the Network Devices module, Netflow / Bandwidth module, the Apppilcations and Servers module and the ServiceDesk module. You may want to provide restricted access to these module to a number of Users in varying permutations. The Users and Roles feature helps you do this and it is advised to understand this feature before configuration of the same. Please refer to the following link for details:
http://www.manageengine.com/it360/help/meitms/getting-started/manage_users_roles.html
Frequency of User synchronisation or importing Users from Active Directory should not be less than 1 day. You may configure this Admin -- General -- Active Directory -- Import Users from Active Directory
Log File configuration
Database management
Heap Size
Cache...
Polling Interval - Performance Data Collection interval and Availability Checks frequency
Data Retention / Archiving
Please refer to the following sections of the Help Documentation for FAQ and Troubleshooting [these could also be a source of best practices tips]:

One way of improving the performance of the Applications and Servers module of IT360 is to use the Downtime Scheduler feature, for such of those servers for which you may want to have a scheduled maintenance: the Data Collection Threads are freed during the scheduled downtimes. These threads can be utilised by other monitors. [Note: Using the Downtime Scheduler feature also avoids the generation of alert notifications during the planned maintenance]
IT360 offers two distinct features related to Polling:
Socket Timeout
One way of reducing the false alarms is to increase the socket timeout option by changing the am.sockettest.timeout value present in <IT360_Home>/applications/conf/AMServer.properties. You may change the value from 5 to say, 10.
Network Availability check
When you use IT360 for network device monitoring, alarms are generated when the url is not available / down. However, you may also see alarms when IT360 is out of network or if the proxy settings are not configured. To avoid such false alarms, you may use the Network Availabilty Check option where you specify a dependable host which is unlikely to go unreachable / go down. Before reporting a monitored resource as down, IT360 checks for the availability of this specified resource and if it is down only then it reports the monitored devices as down.
URL Availability Check
When you use IT360 for URL monitoring, alarms are generated when the url is not available / down. However, you may also see alarms when IT360 is out of network or if the proxy settings are not configured. To avoid such false alarms, you may use the URL Availabilty Check option where you specify a dependable URL which is unlikely to go down. Before reporting a monitored url as down, IT360 checks for the availability of this specified url and if it is down only then it reports the monitored url as down.
Consecutive Polls check
You may use this option to check the number of consecutive polls for which an error existed before actually reporting the error to the IT360 system for alarm notification, etc..You need to configure at Admin -- Servers and Applications -- Alarm Settings --Consecutive Polls Count
You may also specify the size of the log files at <IT360_Home>/applications/working/conf/logging_parameters.conf
When ping timeout happens, the devices are not discovered. You may increase the Timeout value to try and discover the devices. The Timeout value can be set in the following file:
<IT360_Home>/networks/conf/ping.properties
If you want to identify the devices by their Host Names instead of their IP Addresses, you need to set the DNS Server address in the machine that hosts IT360.
It360 supports monitoring of several hundreds of devices across vendors. The corresponding Devices Templates and MIBs are already present in IT360, by default. However, if you want to monitor a New Device [which is outside of the Device Templates list], it is a good practice to create a New Device Template and import the relevant MIBs, well ahead of its monitoring by IT360. This ensures that the New Device is placed under the correct device category.
For Database tuning, Heap size, thread cache, query cache settings, etc., please refer to the following link. This link contains complete details about the tuning aspects of IT360 for optimal performance.
