FileMaker Server Top Call Logging

With the release of FileMaker Server 15 comes the ability to track the heaviest client usage periods. This new feature, named the Top Call Statistics Log, gives server and group administrators the ability to pinpoint the client requests that take the longest, allowing them to investigate any slowdowns in their systems much more quickly and efficiently.

In previous versions of FileMaker server, administrators had the ability to view real-time client statistics on the admin console under the Statistics screen, both for the server as a whole and for individual clients.

These, while certainly useful for seeing when activity was high, didn’t reveal much of the why. When the Top Call Statistics Log is enabled under the “Database Server>Logging” tab, you can delve deeper into the reasons for the high activity. The log describes up to 25 client requests that have the longest elapsed time during the statistics collection interval, which is also specified under the “Database Server>Logging” tab. The Top Call Statistics Log will allow users to see who performed the action, what the operation was, and even the filename, table, layout and field to give them a clearer picture of what the server was processing. Below displays everything the log tracks.

Timestamp Database Server timestamp at the collection interval, using same format as the other log files.
Start Time Timestamp at the start of the remote call (seconds.fraction since the Database Server was started)
End Time Timestamp at the end of the remote call (seconds.fraction since the Database Server was started). The column will be empty if the remote call is in progress.
Total Elapsed Total number of microseconds elapsed for the remote call so far.
Operation The name of the remote call; for example: Query, Upload, or Download.

For some operations, this column includes a task name and the percentage completed; for example:
Query (Indexing 10%).

Target The name of the hosted file that a client has open, with additional data if possible. Possible formats may include:



Elapsed Time Microseconds of elapsed time for the remote call in this collection interval.
Wait Time Time waiting for other clients (in microseconds) for the remote call in this collection interval.
I/O Time Time waiting for disk input/output (in microseconds) for the remote call in this collection interval
Network Bytes In Number of bytes received from the client during this collection interval
Network Bytes Out Number of bytes sent to the client during this collection interval.
Client Name A client name or identifier; for example, an IP address or FileMaker WebDirect client identifier.


The log file is stored under the “/FileMaker Server/Logs/” folder and is named “TopCallStats.log”. This will track the statistics up to the file size specified under the “Database Server>Logging” tab in the admin console. When the file size of the log reaches the specified log size, it is renamed “TopCallStats-old.log” and a new “TopCallStats.log” file is created.

Log File Location

Using TopCallStats.log

The file can be viewed in any application that can read tab-delimited data.

Top Call Excel

It can also be imported directly into a FileMaker solution, using either the “File>Import Records>File” option or using the “Import Records” script step. This allows users to store, find and compare results much more easily and across a large span of time.

Top Call Statistics Logging allows server and group administrators newfound capabilities of discovering their systems’ performances, as well as the information to help determine possible solutions to any inefficiencies they discover. This gives administrators the ability to see the who, what, when and why of any issues they come across and allows easy tracking of any heavy usage issues that may occur. This is just one of the many new features in FileMaker 15 that allows businesses to run their day-to-day operations smoothly.

"We were actually able to add more features than we thought would be possible within our budget. We always experienced a ‘can do’ attitude and DB Services was incredibly patient and easy to work with."
Courtney Hartman
Art Director
"The new FileMaker custom website interface is very user-friendly and easy to follow for our clients. In addition, it is much faster than the old Instant Web Publishing (IWP) interface. Thank you and all the others who have helped us out at DB Services. I am very grateful for the excellent service you provide us. Its nice to know we can call you for help if we have an issue."
Wayne Capek
"We needed a solution that would simplify the administration of our responsibilities under our contract with the State of Indiana. We have seen a dramatic increase across the state in the number of potential foster and adoptive parents that have begun the preparation and training process. This increase has resulted in a significant opportunity for children available for adoption. That’s a big win for everyone! And it’s all because we can refer potential parents to the proper state contacts efficiently and quickly."
Chris Morrison
Executive Director
"Thank you for all of your expertise and valuable help. I am so grateful to have found DB Services."
Linda Findlay
"Thank you for our new database system. We transitioned from a carbon copy paper based system to a digital database. The software has saved us time and money. We used to archive all our jobs in cabinets, now we can look up a job in seconds from anywhere. The software allows us to easily email estimates to our customers in pdf format. In a year there was a return on investment just from eliminating the purchasing of our carbon forms."
Todd Cartmel
"The new system allows us to create and track jobs for customers along with inventory, something we had been doing with separate word and spreadsheet files. Because it’s now so intuitive, new staff members are able to begin using the database immediately without our usual training session and ‘cheat sheets’ for getting around within the file."
