[Solved]Grep remote multiple hosts output to local server

Hello all,
i'm trying to create a report by greping a pattern on multiple remote hosts and creta a simple report,
actually i did this, is ther any better way to do this.
Code:
#!/bin/bash
for host in `cat RemoteHosts`
do
  ssh $host -C 'hostname 2>&1; grep ERROR /var/log/WebServer.log.2019-09-21 | wc -l' >> output
done
# joining each two lines together with single tab between
sed 'N;s/\n/ /' output > JoinedLinesReport.csv
#removing old output file
rm -f output

The report with the above script is the following,
Code:
server1   1345
server2 2345

Is there any way to create it like this?
Code:
HostName Count
server1	        1345
server2	        2345

EDIT: added a new sed to add the line i need.
Thanks any way.
Code:
sed -i '1s/^/HostName Count\n/'  JoinedLinesReport.csv

NAME
asadmin-create-virtual-server, create-virtual-server - adds the named virtual server SYNOPSIS
create-virtual-server --user admin_user [--password admin_password] [--host localhost] [--port 4848] [--secure|-s] [--passwordfile file- name] [--terse=false] [--echo=false] [--interactive=true] --hosts hosts [--httplisteners http_listeners] [--defaultwebmodule default_web_module] [--state on] [--logfile log_file] [--property (name=value)[:name=value]*] virtual_server_id Creates the named virtual server. Virtualization in the Application Server allows multiple URL domains to be served by the same HTTP server process which is listening on multiple host addresses. If the application is available at two virtual servers, they still share the same physical resource pools. This command is supported in remote mode only. OPTIONS
--user authorized domain application server administrative username. --password password to administer the domain application server. --host machine name where the domain application server is running. --port port number of the domain application server listening for administration requests. --secure if true, uses SSL/TLS to communicate with the domain application server. --passwordfile file containing the domain application server password. --terse indicates that any output data must be very concise, typically avoiding human-friendly sentences and favoring well- formatted data for consumption by a script. Default is false. --echo setting to true will echo the command line statement on the standard output. Default is false. --interactive if set to true (default), only the required password options are prompted. --hosts a comma separated (,) list of values allowed in the host request header to select the current virtual server. Each virtual server that is configured to the same connection group must have a unique hosts value for that group. --httplisteners optional; a comma separated (,) list of HTTP listener IDs. Required only for a virtual server that is not the default virtual server. --defaultwebmodule standalone web module associated with this virtual server by default. --state determines whether a virtual server is active (on) or inactive (off or disabled). Default is active (on). When inactive, the virtual server does not service requests. --logfile name of the file where the log has to be written to. --property optional attributes name/value pairs for configuring the connection pool. OPERANDS
virtual_server_id identifies the unique ID for the virtual server to be created. This virtual server ID cannot begin with a number. Example 1: Using create-virtual-server asadmin> create-virtual-server --user admin1 --password adminadmin1 --host pigeon --port 5001 --httplisteners http-listener-1 --defaultwebmodule simple --state on --logfile server.log --property User=admin:Password=admin --hosts sample1,sample2 sample_vs1 Command create-virtual-server executed successfully Where sample_vs1 is the virtual server created. EXIT STATUS
0 command executed successfully 1 error in executing the command asadmin-delete-virtual-server(1AS), asadmin-list-virtual-server(1AS) J2EE 1.4 SDK March 2004 asadmin-create-virtual-server(1AS)
